Reset your XP/2003 password

1. In default, windows XP installation leave administrator account's password as empty, you can try to restart computer to comtrol console and login as administrator. In windows XP, press CTRL+ALT and DEL twice to force to show default login screen.

2. Use ERD Commander 2005 , which is part of winternals's Administrator's Pak. Here it is a flash movie showing how to reset any password on local accounts on your PC including administrators.

3. In windows 2000, deleted "SAM" file under "\System32\Config" folder may allow you to login in with empty password. But this may result a system failure in windows xp and 2003 and cause the system been locked.

4. In windows 2000, if you have access to DOS, changed "logon.scr" under "\System32" to some other file name, and changed "cmd.exe" to "logon.scr", after reboot and wait several minute, you will bring to DOS screen where you can use "net user username userpassword/add" then "net localgroup administrators username/add" command to add a user. But in windows xp (sp2) and windows 2003, you do not have sufficient privilege to run "net user".

5. Use windowskey (part of "Passware Kit Enterprise") published by LostPassword.com.
It requied you burning a floppy driver disk. Then boot computer with windows xp setup cd and press F6 to load third party driver from floppy disk. This will reset administrator password to 12345.

6. Use DreamPackPL to create a bootable CD. Use this CD to boot computer and goto concole,
cd c:\windows\system32
ren sfcfiles.dll sfcfiles.lld
copy H:\i386\pinball.ex_ sfcfiles.dll
Here H is the CD. Then restart computer.

7. sysLinux. Download a image from here and burn it. Then load it up, it will start linux, then following these steps

1. Disk select, tell which disk contains the Windows system. Optionally you will have to load drivers.
2. PATH select, where on the disk is the system?
3. File select, which parts of registry to load, based on what you want to do.
4. Password reset or other registry edit.

8. Startup scripts: Try to make access to the hard disk,

Create a bat file "admin.bat" under "C:\windows\system32\GroupPolicy\MachineScripts\Startup":
net user username userpassword/add
net localgroup administrators username/add
Create script file "scripts.ini" under "C:\windows\system32\GroupPolicy\MachineScripts":

Then reboot the computer.

9. Take out the dard disk and mount to another windows XP. Try to copy the "SAM" file under "\System32\Config" and run L0phtCrack or SAMInside to decrypt. Another way is overwrite this file with the SAM file from "\WINDOWS\repair\sam" folder will reset administrator to empty.
