Possible Duplicate:
Windows 7 Logged on with a temporary profile

I have this serious problem. Whenever I start windows, it says 'this is a temporary login profile. The files you create and update in this profile will be deleted when you log off'.

I have only one login profile of which I am the administrator. All the software I add on login automatically gets deleted when I reboot the system. I am not able to find out whats the problem.

I dont have any other OS used in my system.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Please specify what version of Windows you're using :) – Oliver Salzburg Jul 27 '12 at 13:36
I'm using Windows7 – anaida Jul 27 '12 at 13:37

Which Windows operating system are you using?

There's a guide for Windows 7 - also available here.

Log in with your temporary profile.

Start Registry Editor by typing regedit in the Run dialog/Start Menu find box in Windows 7.

Navigate the following location in the Registry Editor:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

You should be able to see many 'keys' - one with a .bak extension.

Your correct profile key is marked as .bak. Currently your Windows 7 computer is logged in with a fresh profile with the same key. So, rename the new profile key (which does not have the bak extension) and remove .bak from correct profile key. Image link below.

That’s it. Log off and log in with your user name and password. Some profile settings/icons might have been reset, although the profile should be working as normal.

Welcome to Super User! Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. – Oliver Salzburg Jul 27 '12 at 13:36
