no error message no restart or fatal shutdowns. when i login to the windows, as soon as the desktop background shows up. the windows logs off automatically; i think this has to do something with winlogon.exe. any suggestion how to recover from this. i've tried the code "copy userinit.exe wsaupdater.exe" in the recovery console, did not work for me.

till yesterday i did not see any error message but today i saw an error message stating "the windows cannot log me in to my profile because it is being used by another process or service" someting like that. now can anyone tell me whats going on?

Try pressing F8 during erly boot and selecting safe mode and see if you can get in that way.

i've already mentioned above that it doesn't work in safe mode too......

How about if you physically disconnect the internet connection to the pc?
