Anyway, someone with the same problem:
"The only way to delete those problem files is from DOS. You will first need to change the access right for your ACLs using the CACLS command. Once you've changed it for each of the file paths that you wanted to delete, you may delete each files *individually*. After the deletion, you'll need to restart your computer. then your pc should run normal with normal cpu usage hereafter."
I don't think I'm knowledgeable to do this without step-by-step instructions. Is there any user-friendly software that can manage this for me at bootup? Something like Revouninstall?
I'm not on my PC right now, but someone suggested I open the desktop as a window, kill explorer.exe, then try to delete the file in the window. I would have thought the window would vanish after filling explorer.exe(?)
Another solution seems to be to stop windows 7 from extracting metadata:

This solution was inspired by a post regarding a similar problem to mine:
I have had slight issues with explorer.exe on my PC. Occasionally it takes ages to index(?) folder contents. The blue graphic on the file location box takes ages to reach the top and I have to press stop. Once or twice the CPU has gone crazy about that too, forcing me to restart.
Anyway, I don't need all these complex Windows permissions. I'm the only one who uses the PC. I want to be able to do anything I want with all of the files on my system. Is there any way to simplify things? What are all these login profiles for? User, Admin, etc? I only need one.
