When you try to start or restart your Windows XP-based computer, you may receive one of the following error messages:

1.Windows XP could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM

2.Windows XP could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SOFTWARE

3.Stop: c0000218 {Registry File Failure} The registry cannot load the hive (file): \SystemRoot\System32\Config\SOFTWARE or its log or alternate

4.System error: Lsass.exe
When trying to update a password the return status indicates that the value provided as the current password is not correct.

Basically, boot to dos prompt (or recovery console if available) and make backups of the following files:-
c:\windows\system32\config\system (to c:\windows\tmp\system.bak)
c:\windows\system32\config\software (to c:\windows\tmp\software.bak)
c:\windows\system32\config\sam (to c:\windows\tmp\sam.bak)
c:\windows\system32\config\security (to c:\windows\tmp\security.bak)
c:\windows\system32\config\default (to c:\windows\tmp\default.bak)

then delete the above files (not the backups!)
then copy the above files in c:\windows\repair to the c:\windows\system32\config directory

This is assuming that windows is installed into c:\windows, so adjust as required!

restart your computer
