- If there is another Administrator account then use that account to login and change the password
for the problem account.
Note in WinXP Home the builtin Administrator account has by default no password, but is only accessible through safemode, useful if forgotten the password for another account.
Note if the user has encrypted files or e-mail messages, or have stored passwords for websites or network resources, then these will be losts if using an Administrator account to reset the password. - If using Windows XP and have been foreseeing to create password recovery disks, then they can be used: Note Vista also include the option to Create a password reset disk
- Use a 3rd party Password Remover, which is also able to edit the
SAM (Security Accounts Manager) files and reset the password without damaging the other accounts.
Note this will not work for a domain Administrator account, but it can be done:- Use the Password Remover to reset the password for the local Administrator.
- Boot into safemode which disables the Active Directory(AD).
- Login with the local Administrator and then follow the steps described below to change the login screensaver and recovery of password for a domain controller.
- Change the login screensaver to gain access to user management:
- Replace the %systemroot%\System32\Logon.scr with Explorer.exe or Cmd.exe
- If having access to the registry one can instead change the screensaver with this registry value:
[HKEY_USERS\ .Default\ Control Panel\ Desktop]
SCRNSAVE.EXE = "cmd.exe"
ScreenSaveTimeOut = 15 (Default = 900 secs)
ScreenSaveActive = 1 (Default = 0)
More Info MS KB185348
- If having access to the registry one can instead change the screensaver with this registry value:
- Boot WinNT/2k/Xp and wait for the login screensaver (Not touching keyboard / mouse).
- My Computer or Command Prompt will come up after 15 minutes.
- Change the password:
- If using WinNT run %systemroot%\MUSRMGR ( If a Domain Controller %systemroot%\USRMGR )
- If using Win2k run %systemroot%\Compmgmt.msc ( If a Domain Controller %systemroot%\DSA.MSC )
- If using Command Prompt one can also use this command:
NET USER [username] [newpassword]
- Revert the screensaver changes so My Computer or Command Prompt doesn't popup at login.
- Replace the %systemroot%\System32\Logon.scr with Explorer.exe or Cmd.exe
- Replace Sticky keys executable and use sticky keys to open Command Prompt or Windows Explorer (Windows 2000, XP, Vista)
- Replace %systemroot%\System32\sethc.exe with Explorer.exe or Cmd.exe
- Boot Windows and wait for the login screen to show, then press the Shift-key 5 times to activate sticky keys.
- Now change the password like if having replaced the login screensaver (See above).
- Delete the 3 files SAM , SAM.SAV and SAM.LOG in the directory WINNT\System32\Config.
This will erase all accounts with rights and passwords, but the builtin Administrator
account will survive with no password.
Note even if deleting the SAM-files the users profile directories with settings still exists. One can create a new user and change the default profile directory to point to an old profile directory and use the settings stored there.
- If WinNT is installed on FAT16 or 32 partition then use a standard bootdisk for Win9x to access to the partition.
- Use Knoppix Linux CD to boot Linux with NTFS access and registry editor.
- Use Bart's PE CD to boot Windows XP/2003 with NTFS access and registry editor.
- Install a parallel WinNT/2k/Xp and boot the parallel WinNT/2k/Xp and you will have access to the original installation files along with the offline registry.
- If WinXP one can use the Win2k Install CD to login to the Recovery Console without needing a password.
- Take the HDD and put it into another machine running the same or higher version of Windows and access the files and the offline registry using that machine.

Or use the well-known sticky keys trick to reset a forgotten Windows password:
http://www.top-password.com/knowledge/reset-windows-10-password-without-reset-disk.html
Boot your computer from Windows setup DVD, open the Command Prompt and replace sethc.exe with cmd.exe. The next time you get to the login screen, press SHIFT key 5 times will launch an elevated Command Prompt. From there you can reset the password.
Boot your computer from Windows installation DVD, then replace sethc.exe (Sticky Keys app) with cmd.exe. You can then launch a Command Prompt from Windows logon screen and reset your lost password. You can also try some password reset tool like iseepassowrd, ntpassword, ophcrack.
