When you log in to Windows, the computer immediately saves your settings, logs off and returns to the login screen again.

This is the result of a corrupt or invalid registry entry, which may have been changed by a virus or spyware. Therefore you are strongly advised to scan your computer for viruses and spyware as soon as possible.

Try this method if you can start Windows in safe mode:

* Boot into safe mode.
* Click Start, Run and enter regedit
* Expand HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft \Windows NT\CurrentVersion\Winlogon
* Select the Winlogon folder.
* If the right-hand pane contains an entry named OldUserinit:
- delete the entry named Userinit
- rename OldUserinit to Userinit.
* Check that the value of Userinit is "C:\WINDOWS\system32\userinit.exe," (the comma at the end of the string is important.) Note: if your Windows folder is not C:\Windows, modify the path accordingly.

If you have a Microsoft Windows installation CD:

* Perform a repair installation.

Try taking the hard drive and attaching it to another Windows XP computer as a slave, or by using a USB-to-IDE adapter. Alternatively you can try making a BartPE recovery CD and booting the computer from that. Any method can be used that gives you read/write access to the hard drive.

Often, the registry entry referred to above has been changed from userinit.exe to wsaupdater.exe. Therefore you have a good chance of success if you just copy Windows\System32\userinit.exe to Windows\System32\wsaupdater.exe
