XP Home logs off immediately after you log in

[Guest]

Machine starts up normally, goes to the XP Home welcome screen. I click on
one of the two profiles and it starts logging into the profile, as soon as
the wallpaper comes up, it immediately logs back out to the welcome screen.
It also does this in safe mode and also safe mode with command prompt

Any ideas?

Boot into Safe Mode to the Admin account and log in. From there, perform a
System Restore.

If the above is not the case:

This problem turns out to be that the Winlogon userinit entry is being set
to
"wsupdater.exe," and not "userinit.exe,".

Go to Start/Run/Regedit and navigate to this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon.

In the right pane under Userinit, Change the key to read:
C:\Windows\System32\Userinit.exe,

Or download and run the reg file on line 263 (right hand side)

Or:

Place your XP CD in and navigate to the Recovery Console.
Change the C:\Windows prompt to: C:\Windows\System32 and copy userinit.exe
to wsaupdater.exe
