every time I start windows and Log-In a box appear in the upper left corner of the desktop "applying personal settings." It take few seconds and disappear. This didn't happen to me until l updated to the service pack 3 recently. And after that my desktop is not responding at all. I can only access programs by clicking start menu. I can only use the desktop by resetting the process "explorer.exe" then the desktop started to work normally. Do any one know a solution for this? I think winlogon.exe has something to do with this. Thanks in Advance!
