Desktop, etc. problem

Hey guys, I just restarted my laptop awhile ago (running on vista) and when it went on the appearance was in classic mode and an error appeared: Location is not available C;\\Windows\system32\config\systemprofile\Desktop is not accessible. Access denied There are only 4 icons on y desktop right now, the User, Recycle bin, internet explorer and my computer. I dont know what happened…and my laptop has become slower in result of this.. Also most of my programs couldn't open too.. I tried restoring and repairing but nothing happens..I have also updated with the windows update.. Please help

Hello,
Please read this article.
You will see .bak instead of .bad
You may have to do this in safe mode (under the administrator account).

thanks for the quick reply but it didnt want to work =( I followed everything until i got to the profilelist….under profile list there were 4 folders…none of them had the suffix ending in ".bak"… help?
