I had this a while ago. Microsoft have an unbelievably stupid win 7 program that looks for game related art and information, it runs gameux.dll which you can't delete. However, when it fails to find it for GP4 after you have launched it, it runs an infinite loop using the whole CPU!

There is a fix, but it's a batch command you have to run, I'll have a look...
Edit, download and run the bat file from this page, the Google drive link. I think it's the one I used..
