Computer logs out automatically on startup

Does your computer let you log on then immediately log you off?  If this is happening follow these steps to fix the problem yourself. You most likley picked up Malware or are infected with a virus.

First you will need your XP CD so that you can boot into your recovery console.  To do this put the CD in and start the computer.  You might need to hit f12 to boot from the CD.

On the first screen press R to enter the recovery console.  Type in the built in Administrator password to enter the Console. You’ll see the prompt reading C:\Windows (Or any other drive-letter where you’ve installed XP)

Type d: (d: or whatever letter represents your cd drive)

C:\Windows>CD D:

D:\>CD I386

D:\I386>COPY USERINIT.EX_ C:\WINDOWS\SYSTEM32

(you should see 1 files copied successfully)

Type CD C:\WINDOWS\SYSTEM32

C:\WINDOWS\SYSTEM32>RENAME USERINIT.EX_ USERINIT.EXE

C:\WINDOWS\SYSTEM32>COPY USERINIT.EXE WSAUPDATER.EXE

Type Exit to exit the recovery console and reboot.  You should now be able to log back in.  If that worked run regedit from the Run command.

Navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\

In the right pane, you should see

C:\WINDOWS\System32\wsaupdater.exe,

Change it so that it reads:  C:\WINDOWS\System32\userinit.exe (it might already read userinit.exe)

Once verified download Malwarebytes Anti Malware and Perform full scan.

Download and run CCleaner. 

Scan with your antivirus software.  If you need antivirus software check out under my Free Utility Downloads.  Hope this was helpful.
