[Solved] Prepairing your desktop problem, can't log on

I made a fresh install of vista for a upgrade to windows 7, I trasfered all my files vista and it worked perfictly fine. but some how, soon after I noticed everytime I log on, it says preparing your desktop, as if an account was newly created or it couldn't accses ur user profile, it ends up making a temp directory, but after quite a couple minutes It just goes blue and I see my mouse, I am unable to do anything but I can press Ctrl+Alt+Delete and get to task manager and their for create a new task which is comand prompt and use that, I even tried using it to activate the hidden admin account and it dose the same blue screen, and the same happens for all accounts. what can I do to fix it, from
my understanding it's that the OS no longer remembers where the profiles folders are.
