Just want to share this little knowledge in how to address a problem on logging in. in the windows OS.. more specifically this happens in Windows XP computers..here it is
PROBLEM: automatic log off during log in
1. check HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
2. make sure Userinit value is listed.
3. Data field should be c:\windows\system32\userinit.exe.
Note: If that value isn't there and you need to create it, use String Value when you create it.
