... does xp log off as soon as you log on?

... Windows replaces userinit.exe used in logon with its own wsaupdater.exe

... some adaware/av programs also may remove or quarantine wsaupdater.exe thinking that it's harmful

1. Boot using your winxp cd.
2. Enter recovery console.
3. at the command prompt navigate to


4. next type:

copy userinit.exe wsaupdater.exe

5. exit and reboot normally. You should now be able to logon. But you're not done yet!

6. run regedit (start run (type) regedit)

7. find the Userinit key in:

+HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\

8. modify the entry:


so that it reads:


Make sure you have the comma!


expand D:\i386\userinit.ex_ C:\windows\system32\userinit.exe

... D: = xp cdrom
