Windows 7: Please help, temp user account?

Sorry if this is in the wrong section, or if it has been answered before but I really need help. I logged on to my pc to find it saying 'preparing your desktop', and when it has logged on, Windows says that it is a temp account. I've managed to find my documents but my programmes have disappeared? Please, someone out there, help. I use this pc for my student life and I must have hundreds of pounds worth of programmes on there. Please help. Sorry if I haven't suppiled enough information, but I am upset about this

I apologise, I have fixed this now, a simple reboot fixes the PC.

For any other Windows 7 user with this problem, reboot first. I'm sorry if I wasted anyone's time.

You did not waste anyones time, because you were gracious enough to come back and give us the solution, you have taught all of us and thats what sevenforums is all about. I thank you.
