INCREASE PC PERFORMANCE

this one's fr those who r havin a hard time wid there pc slowing down...


MAKE YOUR WINDOWS FAST AS NEVER BEFORE!


DISABLE INDEXING SERVICES

Indexing Services is a small little program that uses large amounts of RAM and can often make a computer endlessly loud and noisy. This system process indexes and updates lists of all the files that are on your computer. It does this so that when you do a search for something on your computer, it will search faster by scanning the index lists. If you don't search your computer often, or even if you do search often, this system service is completely unnecessary. To disable do the following:

1. Go to Start
2. Click Settings
3. Click Control Panel
4. Double-click Add/Remove Programs
5. Click the Add/Remove Window Components
6. Uncheck the Indexing services
7. Click Next


OPTIMISE DISPLAY SETTINGS

Windows XP can look sexy but displaying all the visual items can waste system resources. To optimise:

1.Go to Start
2. Click Settings
3. Click Control Panel
4. Click System
5. Click Advanced tab
6. In the Performance tab click Settings
7. Leave only the following ticked:
- Show shadows under menus
- Show shadows under mouse pointer
- Show translucent selection rectangle
- Use drop shadows for icons labels on the desktop
- Use visual styles on windows and buttons


DISABLE PERFORMANCE COUNTERS

Windows XP has a performance monitor utility which monitors several areas of your PC's performance. These utilities take up system resources so disabling is a good idea.

To disable:

1. download and install the Extensible Performance Counter List
2.Then select each counter in turn in the 'Extensible performance counters' window and clear the 'performance counters enabled' checkbox at the bottom.button below.


SPEEDUP FOLDER BROWSING

You may have noticed that everytime you open my computer to browse folders that there is a slight delay. This is because Windows XP automatically searches for network files and printers everytime you open Windows Explorer. To fix this and to increase browsing significantly:

1. Open My Computer
2. Click on Tools menu
3. Click on Folder Options
4. Click on the View tab.
5. Uncheck the Automatically search for network folders and printers check box
6. Click Apply
7. Click Ok
8. Reboot your computer


IMPROVE MEMORY USAGE

Cacheman Improves the performance of your computer by optimizing the disk cache, memory and a number of other settings.

Once Installed:

1.Go to Show Wizard and select All
2.Run all the wizards by selecting Next or Finished until you are back to the main menu. Use the defaults unless you know exactly what you are doing.
3.Exit and Save Cacheman
4.Restart Windows


OPTIMISE YOUR INTERNET CONNECTION

There are lots of ways to do this but by far the easiest is to run TCP/IP Optimizer.

1. Download and install
2. Click the General Settings tab and select your Connection Speed (Kbps)
3. Click Network Adapter and choose the interface you use to connect to the Internet
4. Check Optimal Settings then Apply
5. Reboot


OPTIMISE YOUR PAGEFILE

If you give your pagefile a fixed size it saves the operating system from needing to resize the page file.

1. Right click on My Computer and select Properties
2. Select the Advanced tab
3. Under Performance choose the Settings button
4. Select the Advanced tab again and under Virtual Memory select Change
5. Highlight the drive containing your page file and make the initial Size of the file the same as the Maximum Size of the file.

Windows XP sizes the page file to about 1.5X the amount of actual physical memory by default. While this is good for systems with smaller amounts of memory (under 512MB) it is unlikely that a typical XP desktop system will ever need 1.5 X 512MB or more of virtual memory. If you have less than 512MB of memory, leave the page file at its default size. If you have 512MB or more, change the ratio to 1:1 page file size to physical memory size.


RUN BOOTVIS - IMPROVE BOOT TIMES

BootVis will significantly improve boot times

1. Download and Run
2. Select Trace
3. Select Next Boot and Driver Trace
4. A Trace Repetitions screen will appear, select Ok and Reboot
5. Upon reboot, BootVis will automatically start, analyze and log your system's boot process. When it's done, in the menu go to Trace and select Optimize System
6. Reboot.
7. When your machine has rebooted wait until you see the Optimizing System box appear. Be patient and wait for the process to complete


REMOVE THE DESKTOP PICTURE

Your desktop background consumes a fair amount of memory and can slow the loading time of your system. Removing it will improve performance.

1. Right click on Desktop and select Properties
2. Select the Desktop tab
3. In the Background window select None
4. Click Ok


REMOVE FONTS FOR SPEED

Fonts, especially TrueType fonts, use quite a bit of system resources. For optimal performance, trim your fonts down to just those that you need to use on a daily basis and fonts that applications may require.

1. Open Control Panel
2. Open Fonts folder
3. Move fonts you don't need to a temporary directory (e.g. C:FONTBKUP?) just in case you need or want to bring a few of them back. The more fonts you uninstall, the more system resources you will gain.


DISABLE UNNECESSARY SERVICES

Because Windows XP has to be all things to all people it has many services running that take up system resources that you will never need. Below is a list of services that can be disabled on most machines:

Alerter
Clipbook
Computer Browser
Distributed Link Tracking Client
Fast User Switching
Help and Support - (If you use Windows Help and Support leave this enabled)
Human Interface Access Devices
Indexing Service
IPSEC Services
Messenger
Netmeeting Remote Desktop Sharing (disabled for extra security)
Portable Media Serial Number
Remote Desktop Help Session Manager (disabled for extra security)
Remote Procedure Call Locator
Remote Registry (disabled for extra security)
Remote Registry Service
Secondary Logon
Routing & Remote Access (disabled for extra security)
Server
SSDP Discovery Service - (Unplug n' Pray will disable this)
Telnet
TCP/IP NetBIOS Helper
Upload Manager
Universal Plug and Play Device Host
Windows Time
Wireless Zero Configuration (Do not disable if you use a wireless network)
Workstation
To disable these services:

Go to Start and then Run and type "services.msc"
Doubleclick on the service you want to change
Change the startup type to 'Disable"


TURN OFF SYSTEM RESTORE

System Restore can be a useful if your computer is having problems, however storing all the restore points can literally take up Gigabytes of space on your hard drive. To turn off System Restore:

Open Control Panel
Click on Performance and Maintenance
Click on System
Click on the System Restore tab
Tick 'Turn off System Restore on All Drives'
Click 'Ok'


DEFRAGMENT YOUR PAGEFILE

Keeping your pagefile defragmented can provide a major performance boost. One of the best ways of doing this is to creat a separate partition on your hard drive just for your page file, so that it doesn't get impacted by normal disk usage. Another way of keeping your pagefile defragmented is to run PageDefrag. This cool little app can be used to defrag your pagefile, and can also be set to defrag the pagefile everytime your PC starts. To install:

Download and Run PageDefrag
Tick "Defrag at next Reboot",
Click "Ok"
Reboot


SPEEDUP FOLDER ACCESS - DISABLE LAST ACCESS UPDATE

If you have a lot of folders and subdirectories on your computer, when you access a directory XP wastes a lot of time updating the time stamp showing the last access time for that directory and for ALL sub directories. To stop XP doing this you need to edit the registry. If you are uncomfortable doing this then please do not attempt.

Go to Start and then Run and type "regedit"
Click through the file system until you get to "HKEY_LOCAL_MACHINESystemCurrentControlSetControlFileSystem"
Right-click in a blank area of the window on the right and select 'DWORD Value'
Create a new DWORD Value called 'NtfsDisableLastAccessUpdate'
Then Right click on the new value and select 'Modify'
Change the Value Data to '1'
Click 'OK'


DISABLE SYSTEM SOUNDS

Surprisingly, the beeps that your computer makes for various system sounds can slow it down, particularly at startup and shut-down. To fix this turn off the system sounds:

Open Control Panel
Click Sounds and Audio Devices
Check Place volume icon in taskbar
Click Sounds Tab
Choose "No Sounds" for the Sound Scheme
Click "No"
Click "Apply"
Click "OK"


IMPROVE BOOT TIMES

A great new feature in Microsoft Windows XP is the ability to do a boot de
fragment. This places all boot files next to each other on the disk to allow for faster booting. By default this option in enables but on some builds it is not so below is how to turn it on.

Go to Start Menu and Click Run
Type in "Regedit" then click ok
Find "HKEY_LOCAL_MACHINESOFTWAREMicrosoftDfrgBootOpt imizeFunction"
Select "Enable" from the list on the right
Right on it and select "Modify"
Change the value to "Y to enable"
Reboot


IMPROVE SWAPFILE PERFORMANCE

If you have more than 256MB of RAM this tweak will considerably improve your performance. It basically makes sure that your PC uses every last drop of memory (faster than swap file) before it starts using the swap file.

Go to Start then Run
Type "msconfig.exe" then ok
Click on the System.ini tab
Expand the 386enh tab by clicking on the plus sign
Click on new then in the blank box type"ConservativeSwapfileUsage=1"
Click OK
Restart PC


MAKE YOUR MENUS LOAD FASTER

This is one of my favourite tweaks as it makes a huge difference to how fast your machine will 'feel'. What this tweak does is remove the slight delay between clicking on a menu and XP displaying the menu.

Go to Start then Run
Type 'Regedit' then click 'Ok'
Find "HKEY_CURRENT_USERControl PanelDesktop"
Select "MenuShowDelay"
Right click and select "Modify'
Reduce the number to around "100"
This is the delay time before a menu is opened. You can set it to "0" but it can make windows really hard to use as menus will open if you just look at them - well move your mouse over them anyway. I tend to go for anywhere between 50-150 depending on my mood


MAKE PROGRAMS LOAD FASTER

This little tweak tends to work for most programs. If your program doesn't load properly just undo the change. For any program:

Right-click on the icon/shortcut you use to launch the program
Select properties
In the 'target' box, add ' /prefetch:1' at the end of the line.
Click "Ok"
Voila - your programs will now load faster.


IMPROVE XP SHUTDOWN SPEED

This tweak reduces the time XP waits before automatically closing any running programs when you give it the command to shutdown.

Go to Start then select Run
Type 'Regedit' and click ok
Find 'HKEY_CURRENT_USERControl PanelDesktop\'
Select 'WaitToKillAppTimeout'
Right click and select 'Modify'
Change the value to '1000'
Click 'OK'
Now select 'HungAppTimeout'
Right click and select 'Modify'
Change the value to '1000'
Click 'OK'
Now find 'HKEY_USERS.DEFAULTControl PanelDesktop'
Select 'WaitToKillAppTimeout'
Right click and select 'Modify'
Change the value to '1000'
Click 'OK'
Now find 'HKEY_LOCAL_MACHINESystemCurrentControlSetControl\'
Select 'WaitToKillServiceTimeout'
Right click and select 'Modify'
Change the value to '1000'
Click 'OK'


SPEED UP BOOT TIMES I

This tweak works by creating a batch file to clear the temp and history folders everytime you shutdown so that your PC doesn't waste time checking these folders the next time it boots. It's quite simple to implement:

1. Open Notepad and create a new file with the following entries:

RD /S /q "C:Documents and Settings"UserName without quotes"Local SettingsHistory"
RD /S /q "C:Documents and SettingsDefault UserLocal SettingsHistory"
RD /S /q "D:Temp" <--"Deletes temp folder, type in the location of your temp folder"

2. Save the new as anything you like but it has to be a '.bat' file e.g. fastboot.bat or deltemp.bat

3. Click 'Start' then 'Run'

4. Type in 'gpedit.msc' and hit 'ok'

5. Click on 'Computer Configuration' then 'Windows Settings'

6. Double-click on 'Scripts' and then on 'Shutdown'

7. Click 'Add' and find the batch file that you created and then press 'Ok'


SPEED UP BOOT TIMES II

When your PC starts it usually looks for any bootable media in any floppy or cd-rom drives you have installed before it gets around to loading the Operating System from the HDD. This can waste valuable time. To fix this we need to make some changes to the Bios.

1. To enter the bios you usually press 'F2' or 'delete' when your PC starts

2. Navigate to the 'Boot' menu

3. Select 'Boot Sequence'

4. Then either move your Hard drive to the top position or set it as the 'First Device'

5. Press the 'Escape' key to leave the bios. Don't forget to save your settings before exiting

Note: Once this change has been made, you won't be able to boot from a floppy disc or a CD-rom. If for some strange reason you need to do this in the future, just go back into your bios, repeat the steps above and put your floppy or CD-rom back as the 'First Device'


SPEED UP BOOT TIMES III

When your computer boots up it usually has to check with the network to see what IP addresses are free and then it grabs one of these. By configuring a manually assigned IP address your boot time will improve. To do this do the following:

1. Click on 'Start' and then ''Connect To/Show All Connections'

2. Right-click your network adapter card and click 'Properties'.

3. On the 'General' tab, select 'TCP/IP' in the list of services and click 'Properties'

4.I n the TCP/IP properties, click 'Use the following address' and enter an IP address for your PC. If you are using a router this is usually 192.168.0.xx or 192.168.1.xx. If you are not sure what address you could check with your ISP or go to 'Start/run' and type 'cmd' and then 'ipconfig/all'. This will show your current IP settings which you will need to copy.

5. Enter the correct details for 'Subnet mask', 'Default gateway' and 'DNS Server'. Again if you are not sure what figures to enter use 'ipconfig/all' as in stage 4.


FREE UP MEMORY

I found this useful app via FixMyXP. ClearMem Is an Excellent Tool for speeding up your XP Computer (especially if your system has been on for awhile and you have a lot of applications open). What it does, is it Forces pages out of physical memory and reduces the size of running processes if working sets to a minimum. When you run this tool, the system pauses because of excessive high-priority activity associated with trimming the working sets. To run this tool, your paging file must be at least as large as physical memory. To Check your Paging File:

1. Go to your control panel, then click on 'System', then go to the 'Advanced' Tab, and Under 'Performance' click 'Settings' then the 'Advanced' Tab

2. On the Bottom you should see 'Virtual Memory' and a value. This is the value that must be at least as large as how much memory is in your system.

3. If the Virtual Memory Value is smaller than your system memory, click Change and change the Min Virtual Memory to a number that is greater than your total system memory, then click 'Set' and Reboot.

4. Once you have rebooted install ClearMem


ENSURE XP IS USING DMA MODE

XP enables DMA for Hard-Drives and CD-Roms by default on most ATA or ATAPI (IDE) devices. However, sometimes computers switch to PIO mode which is slower for data transfer - a typical reason is because of a virus. To ensure that your machine is using DMA:

1. Open 'Device Manager'

2. Double-click 'IDE ATA/ATAPI Controllers'

3. Right-click 'Primary Channel' and select 'Properties' and then 'Advanced Settings'

4. In the 'Current Transfer Mode' drop-down box, select 'DMA if Available' if the current setting is 'PIO Only'


ADD CORRECT NETWORK CARD SETTINGS

Some machines suffer from jerky graphics or high CPU usage even when a machine is idle. A possible solution for this, which, can also can help network performance is to:

1. RightClick 'My Computer'

2. Select 'Manage'

3. Click on 'Device Manager'

4. DoubleClick your network adaptor under 'Network Adapters'

5. In the new window, select the 'Advanced' tab

6. Select 'Connection Type' and select the correct type for your card and then Reboot


REMOVE ANNOYING DELETE CONFIRMATION MESSAGES

Although not strictly a performance tweak I love this fix as it makes my machine 'feel' faster. I hate the annoying 'are you sure?' messages that XP displays, especially if I have to use a laptop touchpad to close them. To remove these messages:

1. Right-click on the 'Recycle Bin' on the desktop and then click 'Properties'

2. Clear the 'Display Delete Confirmation Dialog' check box and click 'Ok'

If you do accidently delete a file don't worry as all is not lost. Just go to your Recycle Bin and 'Restore' the file.


DISABLE PREFETCH ON LOW MEMORY SYSTEMS

Prefetch is designed to speed up program launching by preloading programs into memory - not a good idea is memory is in short supply, as it can make programs hang. To disable prefetch:

1. Click 'Start' then 'Run'

2. Type in 'Regedit' then click 'Ok'

3. Navigate to 'HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementPrefetchParameters\'

4. Right-click on "EnablePrefetcher" and set the value to '0'

5. Reboot.


I hope you find these changes useful. :D





This tip is only recommended if you have 256MB RAM or higher.

Follow these steps:

* Run SYSEDIT.EXE from the Run command.
* Expand the system.ini file window.
* Scroll down almost to the end of the file till you find a line called [386enh].
* Press Enter to make one blank line, and in that line type

Irq14=4096

Note: This line IS CASE SENSITIVE!!!

* Click on the File menu, then choose Save.
* Close SYSEDIT and reboot your computer.
* Done. Speed improvement will be noticed after the computer reboots.

WAYS TO SPEED UP XP::NOT ONLY DEFRAG

1.) To decrease a system's boot time and increase system performance, use the money you save by not buying defragmentation software -- the built-in Windows defragmenter works just fine -- and instead equip the computer with an Ultra-133 or Serial ATA hard drive with 8-MB cache buffer.

2.) If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.

3.) Ensure that Windows XP is utilizing the NTFS file system. If you're not sure, here's how to check: First, double-click the My Computer icon, right-click on the C: Drive, then select Properties. Next, examine the File System type; if it says FAT32, then back-up any important data. Next, click Start, click Run, type CMD, and then click OK. At the prompt, type CONVERT C: /FS:NTFS and press the Enter key. This process may take a while; it's important that the computer be uninterrupted and virus-free. The file system used by the bootable drive will be either FAT32 or NTFS. I highly recommend NTFS for its superior security, reliability, and efficiency with larger disk drives.

4.) Disable file indexing. The indexing service extracts information from documents and other files on the hard drive and creates a "searchable keyword index." As you can imagine, this process can be quite taxing on any system.

The idea is that the user can search for a word, phrase, or property inside a document, should they have hundreds or thousands of documents and not know the file name of the document they want. Windows XP's built-in search functionality can still perform these kinds of searches without the Indexing service. It just takes longer. The OS has to open each file at the time of the request to help find what the user is looking for.

Most people never need this feature of search. Those who do are typically in a large corporate environment where thousands of documents are located on at least one server. But if you're a typical system builder, most of your clients are small and medium businesses. And if your clients have no need for this search feature, I recommend disabling it.

Here's how: First, double-click the My Computer icon. Next, right-click on the C: Drive, then select Properties. Uncheck "Allow Indexing Service to index this disk for fast file searching." Next, apply changes to "C: subfolders and files," and click OK. If a warning or error message appears (such as "Access is denied"), click the Ignore All button.

5.) Update the PC's video and motherboard chipset drivers. Also, update and configure the BIOS. For more information on how to configure your BIOS properly, see this article on my site.

6.) Empty the Windows Prefetch folder every three months or so. Windows XP can "prefetch" portions of data and applications that are used frequently. This makes processes appear to load faster when called upon by the user. That's fine. But over time, the prefetch folder may become overloaded with references to files and applications no longer in use. When that happens, Windows XP is wasting time, and slowing system performance, by pre-loading them. Nothing critical is in this folder, and the entire contents are safe to delete.

7.) Once a month, run a disk cleanup. Here's how: Double-click the My Computer icon. Then right-click on the C: drive and select Properties. Click the Disk Cleanup button -- it's just to the right of the Capacity pie graph -- and delete all temporary files.

8.) In your Device Manager, double-click on the IDE ATA/ATAPI Controllers device, and ensure that DMA is enabled for each drive you have connected to the Primary and Secondary controller. Do this by double-clicking on Primary IDE Channel. Then click the Advanced Settings tab. Ensure the Transfer Mode is set to "DMA if available" for both Device 0 and Device 1. Then repeat this process with the Secondary IDE Channel.

9.) Upgrade the cabling. As hard-drive technology improves, the cabling requirements to achieve these performance boosts have become more stringent. Be sure to use 80-wire Ultra-133 cables on all of your IDE devices with the connectors properly assigned to the matching Master/Slave/Motherboard sockets. A single device must be at the end of the cable; connecting a single drive to the middle connector on a ribbon cable will cause signaling problems. With Ultra DMA hard drives, these signaling problems will prevent the drive from performing at its maximum potential. Also, because these cables inherently support "cable select," the location of each drive on the cable is important. For these reasons, the cable is designed so drive positioning is explicitly clear.

10.) Remove all spyware from the computer. Use free programs such as AdAware by Lavasoft or SpyBot Search & Destroy. Once these programs are installed, be sure to check for and download any updates before starting your search. Anything either program finds can be safely removed. Any free software that requires spyware to run will no longer function once the spyware portion has been removed; if your customer really wants the program even though it contains spyware, simply reinstall it. For more information on removing Spyware visit this Web Pro News page.

11.) Remove any unnecessary programs and/or items from Windows Startup routine using the MSCONFIG utility. Here's how: First, click Start, click Run, type MSCONFIG, and click OK. Click the StartUp tab, then uncheck any items you don't want to start when Windows starts. Unsure what some items are? Visit the WinTasks Process Library. It contains known system processes, applications, as well as spyware references and explanations. Or quickly identify them by searching for the filenames using Google or another Web search engine.

12.) Remove any unnecessary or unused programs from the Add/Remove Programs section of the Control Panel.

13.) Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations. Windows XP offers many different settings in this area. Here's how to do it: First click on the System icon in the Control Panel. Next, click on the Advanced tab. Select the Settings button located under Performance. Feel free to play around with the options offered here, as nothing you can change will alter the reliability of the computer -- only its responsiveness.

14.) If your customer is an advanced user who is comfortable editing their registry, try some of the performance registry tweaks offered at Tweak XP.

15.) Visit Microsoft's Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.

16.) Update the customer's anti-virus software on a weekly, even daily, basis. Make sure they have only one anti-virus software package installed. Mixing anti-virus software is a sure way to spell disaster for performance and reliability.

17.) Make sure the customer has fewer than 500 type fonts installed on their computer. The more fonts they have, the slower the system will become. While Windows XP handles fonts much more efficiently than did the previous versions of Windows, too many fonts -- that is, anything over 500 -- will noticeably tax the system.

18.) Do not partition the hard drive. Windows XP's NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operating system. The same excuses people offer for using partitions apply to using a folder instead. For example, instead of putting all your data on the D: drive, put it in a folder called "D drive." You'll achieve the same organizational benefits that a separate partition offers, but without the degradation in system performance. Also, your free space won't be limited by the size of the partition; instead, it will be limited by the size of the entire hard drive. This means you won't need to resize any partitions, ever. That task can be time-consuming and also can result in lost data.

19.) Check the system's RAM to ensure it is operating properly. I recommend using a free program called MemTest86. The download will make a bootable CD or diskette (your choice), which will run 10 extensive tests on the PC's memory automatically after you boot to the disk you created. Allow all tests to run until at least three passes of the 10 tests are completed. If the program encounters any errors, turn off and unplug the computer, remove a stick of memory (assuming you have more than one), and run the test again. Remember, bad memory cannot be repaired, but only replaced.

20.) If the PC has a CD or DVD recorder, check the drive manufacturer's Web site for updated firmware. In some cases you'll be able to upgrade the recorder to a faster speed. Best of all, it's free.

21.) Disable unnecessary services. Windows XP loads a lot of services that your customer most likely does not need. To determine which services you can disable for your client, visit the Black Viper site for Windows XP configurations.

22.) If you're sick of a single Windows Explorer window crashing and then taking the rest of your OS down with it, then follow this tip: open My Computer, click on Tools, then Folder Options. Now click on the View tab. Scroll down to "Launch folder windows in a separate process," and enable this option. You'll have to reboot your machine for this option to take effect.

23.) At least once a year, open the computer's cases and blow out all the dust and debris. While you're in there, check that all the fans are turning properly. Also inspect the motherboard capacitors for bulging or leaks. For more information on this leaking-capacitor phenomena, you can read numerous articles on my site.


Following any of these suggestions should result in noticeable improvements to the performance and reliability of your customers' computers. If you still want to defrag a disk, remember that the main benefit will be to make your data more retrievable in the event of a crashed drive.

HACKING BASICS - FAQ'S

How do I hack?-
There is no easy way how to hack. Google is your best friend.. REMEMBER THAT! Read any information you can find on hacking. Read hacking forums and check out hacking websites. Learn a programming language like C++. Get a book like Hacking for Dummies which will teach you alot.

What do I need to be able to hack? -
Firstly you need to understand how your computers operating system works, networks and protocols works, security settings and general PC knowledge. After you understand how it works you need hacking tools which helps you to hack.

What is command prompt (cmd- the little dos Windows)? -
Go START, RUN and type in: "cmd"What can I do in cmd? - You can can do various things with it like run exploits or do a ping request.

Why does some of the hacking tools I download just close itself when I open them? -
Lot's of hacking tools are DOS based and has to be run through CMD. If you double click on the program it will open a DOS box and automaticly close the box. From CMD you can navigate to the directory which your hacking tool is stored in and run it from there. Other hacking tools are GUI ( graphical user interface ) based and it will open like a normal Windows based program.

What is a IP address? -
Every computer connected to the Internet or some network has a IP address. Goto START, RUN and type in "cmd" then type in "ipconfig" it will show you your IP adress or adresses. It will look something like this : 81.35.99.84. IP = internet protocol.

How do I find someone's IP adress? - Look further down in this tutorial and use IPSTEALER

What can I do with a IP? -
Well you need someone's IP before you can hack, portscan or DOS them.

What is IP ping ? -
It's a command you can use to check if someone's IP address is online, to check it they connected to the Internet or a network. In command prompt type in "ping 192.168.0.21" - this will show you something like this : Pinging 192.168.0.21 with 32 bytes of data:Reply from 192.168.0.21: bytes=32 time<1ms TTL=128Reply from 192.168.0.21: bytes=32 time<1ms TTL=128Reply from 192.168.0.21: bytes=32 time<1ms TTL=128Reply from 192.168.0.21: bytes=32 time<1ms TTL=128Ping statistics for 192.168.0.21:Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),Approximate round trip times in milli-seconds:Minimum = 0ms, Maximum = 0ms, Average = 0msThat means you can succesfully PING IP 192.168.0.21 which means the IP is online. If you get a message "request timed out" it means the IP is not online. Bytes=32 is the ammount of data which was sent to the host. Time<1ms is the time the host took to reply.

Why can't I ping a certain IP? -
Either the IP is not online/ in use or the person your trying to ping is running a firewall which blocks ping requests or maybe your firewall is blocking outgoing ping requests

What is 127.0.0.1 IP? - It is your PC's local loopback IP address.

Why do I have two IP addresses when I do a ipconfig? -
Well if your on a local LAN (Local area network) you will have a IP like 192.168.0.1. If your also directly connected to the internet you will have another IP address like 80.87.34.56. 192.168.0.1 is your local IP which you use to comunicate with your local internet network (lan) and 80.87.34.56 is your internet IP.

What is a static and dynamic IP address? -
Static means permanent set IP address - like a website will have a static IP address, it never changes. Dynamic means temporary IP address - dailing up to the Internet with a modem or most ADSL connections has dynamic IP's. Everytime you logon to the Internet your ISP ( Internet Service Provider ) will issue you a new IP address.

I have sent someone a trojan but I cannot connect to their PC? -
Either they are running a firewall which blocks you from connecting to their PC, or they are connected to the internet through a router.

What do I do when someone is behind a router and I want to control their PC with a trojan? - You will need to use a trojan which uses reverse connections - meaning you don't connect to the host, the host connects to you. Bifrost is a trojan which has the mentioned function. Remember when someone is behind a router and your using IPstealer to get hold of their IP address, you are actually getting their routers IP, not their actual PC's IP. The router will have the persons internet IP (WAN IP) and their PC will have a difirent IP - their LAN IP.

How do I check if my own PC is infected with a trojan? -
Do a port scan on your PC and check which ports are open. If you find any open ports in this trojan port list you might be infected with a trojan. Download the trojan you think you might be infected with and connect to that specified port.

What is a router? -
A device which is used to route data on a network. a Router decides where certain traffic should be sent to.

What is a firewall? -
Its a software or hardware device which can block or permit certain ports or IP's or certain kinds of data.

What is a port and what can I do with it? -
Every program running on your PC which has some network function uses a specific port to send an receive data though. If you do a port scan you will see which ports are open on the host you scanned. Port 80 is normally a web server. Port 21 a FTP server ect ect.. Trojans also uses ports. Check this list of trojan ports, if you find an open port in this list, the host might be infected with a trojan, download the trojan and try connecting to the port.

How do I do a port scan? -
You need a program like superscan to do a portscan. Then all you do is add the ip you want to scan.Why do you want to scan ports? - If you scan a PC with a port scanner, it will show you which programs or services are running on the PC.Common ports:
Ping : 7
Systat : 11
Time : 13
NetStat : 15
SSH : 22
Telnet : 23
SMTP : 25
Whois : 43
Finger : 79
HTTP : 80
POP : 110

What is an exploit? -
It's a poorly coded piece in software which you can use to gain access to the system. There is many exploits available for the various MS Windows's out there.

How do I use a exploit? -
You first need to compile the exploit with a program like Bloodshed C++ compiler. Then you can start the exploit through command prompt and see if the system your trying to exploit is vulnerable to that specific exploit. Scroll down for more information about exploits.

What is a exploit POC? - POC stands for proof of concept and it the proof that a exploit works.

What is a DOS attack? -
It is when too much data is being sent to a host and it cannot handle all the data and disconnects from the Internet.

How do I see what connections is currently made to my PC? -
In cmd type in "netstat" - it will show you IP addresses of connections to your PC and what port it is using.

What is a MAC address? -
Its a hard coded number, almost like a name which is embedded into a network card. It identifies the manufacturer of the card and a unique number for the card. No two network cards in the world has the same MAC address.

How do I find out my own or someone else's MAC address? -
Your own MAC = Goto cmd and type in "ipconfig /all" MAC address looks something like this : 00-13-20-A3-0B-4CSomeone else's MAC address you need their IP address and then goto cmd and type in "nbtstat -a 192.168.0.5" or whatever IP they use. This will show you their MAC address as well as their currently logged on user.

What is a Windows Registry and how do I access it? -
Its where Windows stores most of the configurations of your operating system and most programs installed. You might used it to make a trojan server file you uploaded to the PC run automaticly when Windows starts up. To access the registry go START, RUN and type in "regedit"Carefull what you change in the registry, it might screw up you PC.. First make a backup of the registry.

How do I hack a webpage/ web server? -
Read the IIS hacking tutorial in the MISC download section on Windows Hacker. Remember not all webservers run IIS!

What is IIS? -
It is Microsoft's web server. IIS - Internet information server. Most webservers run on port 80.

How do I check if a website is running on IIS? -
Telnet to the website URL through CMD - "telnet www.siteyouwanttocheck.com 80"

What is telnet?-
Program which can be used to connect to remote computers or routers and to run commands by simply typing them in its window.

How do I hack into a Gmail, Yahoo or Hotmail email account? -
Every now and then someone discovers a way to get into those email servers, but the service provider fixes the security hole so fast, there is no straight answer for that. Best way is to install a keylogger on the victims PC and get their login details. Otherwise download THIS program which you can use to brute force a hotmail account.

How do I hack into a POP3 email account? -
Hydra 5.3 is a program which you can use to crack POP3 accounts. You will need a wordlist which Hydra will use to crack the POP3 password.

What is a keylogger? -
It is a program you install on someone's PC which captures every key that is pressed on their keyboard which is emailed to you or stored into a file.

How do I get the administrator account password while logged in to the PC? -
Locally run a program like Adminhack for local administrator account cracking. If you need to do it remotely run a program like Venom or Starbrute.

What is a SAM file? -
SAM file is the file which stores all the user accounts and their password hashes like the Administrator account. SAM file is stored in "C:\WINDOWS\system32\config" but it is locked and inaccessable while you are busy using Windows - meaning you can't copy it while your in Windows. You need to boot up with another operating system like NTFSDOS or Linux with NTFS support. When you copied the SAM file you can crack the passwords stored in the SAM file with a program like LC5. With Pwdump6 it is possible to get access to the SAM file while logged into windows. It can also connect to a remote PC and grab the password hashes from the SAM file. Administrator account is needed.

How do I reset a administrator or some other account password on Win2K/WinXP/WinNT/Win2003? - Download Offline NT Password & Registry Editor which you can use to create a bootup disk or CD and then boot up the PC and then you can reset the password. Just remember that this program will not show you the password, you can only change the password.

How do I crack a administrator password? - If you need to crack a administrator password you will need to copy the SAM file to another machine and crack it. Download this NTXP-Cracker program which has included everything you need to boot up the PC, copy the SAM file and crack the SAM file on another machine.

How do I find out what operating system does my target run? -
Download Detect and use it against your targets IP address.

HACK MANY WEBSITES IN FEW SECONDS

recntly while browsing thru the net i came across this article which i thought to be interesting

hack many websites in few seconds.

this is nt trick .this is a total basic concept based very explosive information .
see if u vant 2 know d technique directly then u can jump on d red lines nd if u vant 2 understand whole d condcept then u shud read whole d stuff.oki?

see,dis moment in dis world nearly 65% sites r being hosted by apache server[linux based]nd 25% r based on iis[microsoft server .ohi...then bcoz linux is free nd hosting is free der most of d person r using linux hosting it is free der4 very secure whether iis is less secured ...now.

we vl learn 2 hack microsoft server hosting based websites.then this moment microsoft is using iis version 7 nd d trick i am going 2 tell u works only on iis5 but it still works on many websites.i hv hacked many nd many websites till d moment nd even u vl do also.
now plz read very carefuly.
wenever we type ../
i mean dot dot slash in a website name then we jump on 1 more level means suppose that a website has been made .d person who is making suppose that he has made a login page 4 dealing by his official persons then definetaly he vl nt show dis page 2 all users ,he vl hide it but on d iis server ..iis server has put dis page on most uppar side of dt website ..oki?then all d passwords nd login information ,dis is also saved in website memory.nd we can nt see dt page but wen we type ../
we reach a page up....then d method is


wenever u hv 2 hack a website just go on thats login link..i mean click on login nd if u watching der something written index.php?page=bla bla bla
then after of bla bla bla type
../etc/password
nd do click .if done then ok..if nt then type after of bla bla bla
../../etc/password
nd again enter if got d password list then ok nd if nt then in next try type one more
../,i mean like dis after of bla bla bla
../../../etc/password again enter nd try like dis untill u dont get d password nd login list ..d trick vl work only on small site ..dont imagine reliance,rapidshare,windows type site 2 be hacked by dis methode.....

preocessing in background-------------->wenever u tyope
../
u reach on 1 more page up nd thus as much type u vl type dis string u vl reach mor e nd more up ...start typing nd start hacking ..enjoi frends ...most of d websites shud be hacked by u now..

Delete an"undeletable file"

Open a Command Prompt window and leave it open.Close all open programs.Click Start, Run and enter TASKMGR.EXEGo to the Processes tab and End Process on Explorer.exe.Leave Task Manager open.Go back to the Command Prompt window and change to the directory the AVI (or other undeletable file) is located in.At the command prompt type DEL where is the file you wish to delete.Go back to Task Manager, click File, New Task and enter EXPLORER.EXE to restart the GUI shell.Close Task Manager.

Or you can try this

Open Notepad.exeClick File>Save As..>l

ocate the folder where ur undeletable file is

Choose 'All files' from the file type box

click once on the file u wanna delete so its name appears in the 'filename' box

put a " at the start and end of the filename(the filename should have the extension of the undeletable file so it will overwrite it)
click save,
It should ask u to overwrite the existing file, choose yes and u can delete it as normal
Here's a manual way of doing it. I'll take this off once you put into your first post zain.
1. Start
2. Run
3. Type: command
4. To move into a directory type: cd c:\*** (The stars stand for your folder)
5. If you cannot access the folder because it has spaces for example Program Files or Kazaa Lite folder you have to do the following. instead of typing in the full folder name only take the first 6 letters then put a ~ and then 1 without spaces. Example: cd c:\progra~1\kazaal~1
6. Once your in the folder the non-deletable file it in type in dir - a list will come up with everything inside.
7. Now to delete the file type in del ***.bmp, txt, jpg, avi, etc... And if the file name has spaces you would use the special 1st 6 letters followed by a ~ and a 1 rule. Example: if your file name was bad file.bmp you would type once in the specific folder thorugh command, del badfil~1.bmp and your file should be gone. Make sure to type in the correct extension.

10 ways why your pc crashes and u must know it

Fatal error: the system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications.
"You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening?

1. Hardware conflict

The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.

For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself.
If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:

* Start-Settings-Control Panel-System-Device Manager.

Often if a device has a problem a yellow '!' appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it.
Sometimes a device might share an IRQ with something described as 'IRQ holder for PCI steering'. This can be ignored. The best way to fix this problem is to remove the problem device and reinstall it.

Sometimes you may have to find more recent drivers on the internet to make the device function properly. A good resource is www.driverguide.com. If the device is a soundcard, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).

When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to discharge any static electricity.

To be fair to Mcft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out of them. There are plans to increase the number of IRQs in future designs.

2. Bad Ram

Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.

But a fatal error caused by Ram might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked.

One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged.

Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble.

EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmes.

3. BIOS settings

Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up.

Once inside the BIOS, great care should be taken. It is a good idea to write down on a piece of paper all the settings that appear on the screen. That way, if you change something and the computer becomes more unstable, you will know what settings to revert to.

A common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS latency of 3. Newer SDRam has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze the computer's display.

Mcft Windows is better at allocating IRQ numbers than any BIOS. If possible set the IRQ numbers to Auto in the BIOS. This will allow Windows to allocate the IRQ numbers (make sure the BIOS setting for Plug and Play OS is switched to 'yes' to allow Windows to do this.).
4. Hard disk drives

After a few weeks, the information on a hard disk drive starts to become piecemeal or fragmented. It is a good idea to defragment the hard disk every week or so, to prevent the disk from causing a screen freeze. Go to

* Start-Programs-Accessories-System Tools-Disk Defragmenter

This will start the procedure. You will be unable to write data to the hard drive (to save it) while the disk is defragmenting, so it is a good idea to schedule the procedure for a period of inactivity using the Task Scheduler.

The Task Scheduler should be one of the small icons on the bottom right of the Windows opening page (the desktop).

Some lockups and screen freezes caused by hard disk problems can be solved by reducing the read-ahead optimisation. This can be adjusted by going to

* Start-Settings-Control Panel-System Icon-Performance-File System-Hard Disk.

Hard disks will slow down and crash if they are too full. Do some housekeeping on your hard drive every few months and free some space on it. Open the Windows folder on the C drive and find the Temporary Internet Files folder. Deleting the contents (not the folder) can free a lot of space.

Empty the Recycle Bin every week to free more space. Hard disk drives should be scanned every week for errors or bad sectors. Go to

* Start-Programs-Accessories-System Tools-ScanDisk

Otherwise assign the Task Scheduler to perform this operation at night when the computer is not in use.

5. Fatal OE exceptions and VXD errors

Fatal OE exception errors and VXD errors are often caused by video card problems.

These can often be resolved easily by reducing the resolution of the video display. Go to

* Start-Settings-Control Panel-Display-Settings

Here you should slide the screen area bar to the left. Take a look at the colour settings on the left of that window. For most desktops, high colour 16-bit depth is adequate.

If the screen freezes or you experience system lockups it might be due to the video card. Make sure it does not have a hardware conflict. Go to

* Start-Settings-Control Panel-System-Device Manager

Here, select the + beside Display Adapter. A line of text describing your video card should appear. Select it (make it blue) and press properties. Then select Resources and select each line in the window. Look for a message that says No Conflicts.

If you have video card hardware conflict, you will see it here. Be careful at this point and make a note of everything you do in case you make things worse.

The way to resolve a hardware conflict is to uncheck the Use Automatic Settings box and hit the Change Settings button. You are searching for a setting that will display a No Conflicts message.

Another useful way to resolve video problems is to go to

* Start-Settings-Control Panel-System-Performance-Graphics

Here you should move the Hardware Acceleration slider to the left. As ever, the most common cause of problems relating to graphics cards is old or faulty drivers (a driver is a small piece of software used by a computer to communicate with a device).

Look up your video card's manufacturer on the internet and search for the most recent drivers for it.

6. Viruses

Often the first sign of a virus infection is instability. Some viruses erase the boot sector of a hard drive, making it impossible to start. This is why it is a good idea to create a Windows start-up disk. Go to

* Start-Settings-Control Panel-Add/Remove Programs

Here, look for the Start Up Disk tab. Virus protection requires constant vigilance.

A virus scanner requires a list of virus signatures in order to be able to identify viruses. These signatures are stored in a DAT file. DAT files should be updated weekly from the website of your antivirus software manufacturer.

An excellent antivirus programme is McAfee VirusScan by Network Associates ( www.nai.com). Another is Nod32, made by Eset ( www.eset.com).

7. Printers

The action of sending a document to print creates a bigger file, often called a postscript file.

Printers have only a small amount of memory, called a buffer. This can be easily overloaded. Printing a document also uses a considerable amount of CPU power. This will also slow down the computer's performance.

If the printer is trying to print unusual characters, these might not be recognised, and can crash the computer. Sometimes printers will not recover from a crash because of confusion in the buffer. A good way to clear the buffer is to unplug the printer for ten seconds. Booting up from a powerless state, also called a cold boot, will restore the printer's default settings and you may be able to carry on.

8. Software

A common cause of computer crash is faulty or badly-installed software. Often the problem can be cured by uninstalling the software and then reinstalling it. Use Norton Uninstall or Uninstall Shield to remove an application from your system properly. This will also remove references to the programme in the System Registry and leaves the way clear for a completely fresh copy.

The System Registry can be corrupted by old references to obsolete software that you thought was uninstalled. Use Reg Cleaner by Jouni Vuorio to clean up the System Registry and remove obsolete entries. It works on Windows 95, Windows 98, Windows 98 SE (Second Edition), Windows Millennium Edition (ME), NT4 and Windows 2000.

Read the instructions and use it carefully so you don't do permanent damage to the Registry. If the Registry is damaged you will have to reinstall your operating system. Reg Cleaner can be obtained from www.jv16.org.

Often a Windows problem can be resolved by entering Safe Mode. This can be done during start-up. When you see the message "Starting Windows" press F4. This should take you into Safe Mode.

Safe Mode loads a minimum of drivers. It allows you to find and fix problems that prevent Windows from loading properly.

Sometimes installing Windows is difficult because of unsuitable BIOS settings. If you keep getting SUWIN error messages (Windows setup) during the Windows installation, then try entering the BIOS and disabling the CPU internal cache. Try to disable the Level 2 (L2) cache if that doesn't work.

Remember to restore all the BIOS settings back to their former settings following installation.

9. Overheating

Central processing units (CPUs) are usually equipped with fans to keep them cool. If the fan fails or if the CPU gets old it may start to overheat and generate a particular kind of error called a kernel error. This is a common problem in chips that have been overclocked to operate at higher speeds than they are supposed to.

One remedy is to get a bigger better fan and install it on top of the CPU. Specialist cooling fans/heatsinks are available from www.computernerd.com or www.coolit.com

CPU problems can often be fixed by disabling the CPU internal cache in the BIOS. This will make the machine run more slowly, but it should also be more stable.

10. Power supply problems

With all the new construction going on around the country the steady supply of electricity has become disrupted. A power surge or spike can crash a computer as easily as a power cut.

If this has become a nuisance for you then consider buying a uninterrupted power supply (UPS). This will give you a clean power supply when there is electricity, and it will give you a few minutes to perform a controlled shutdown in case of a power cut.

It is a good investment if your data are critical, because a power cut will cause any unsaved data to be lost.
