Very simple fix in Windows 7. Go to the follow directory and delete everything below it and restart your computer. It will solve your problem. Note that everything probably wont delete, don’t worry about that.
C:\Users\”yourprofilename”\AppData\Local\Temp\
“yourprofilename” is the name you gave your computer account (should not have double quotes in it. Note also that ...\AppData is hidden, so you’ll need to type it in as you path to it.
You can also delete everything in the following directory too, but only do this if you still have the problem.
C:\Users\farrp\AppData\Local\Microsoft\Windows\Temporary Internet Files\
Or simply go to the “Run” box (or the “Search programs and files” box) and type in “%temp%” (without the quotes) ;’)
