Hi,
I would suggest you to go in your Temp folder and delete every .TMP files (or more simple, delete everything, but you might lose some saved username/passwords in some programs or other things like that).
The Temp folder should be located at "C:\Users\YOUR_USERNAME\AppData\Local\Temp".
If you can't find the folder, press Windows key + R at the same time, type "appdata" in the Run window and press enter.
