Having trouble preventing thumbnails from being cached

Hi, I am using Windows 7 64 bit ultimate, I have tried many methods to prevent thumbs from being cached and so far none of them have worked.

1) First I tried using disk cleaner to remove thumbnails, but the thumbs.db files keep getting recreated in C:\Users\User-Name\AppData\Local\Microsoft\Windows\Explorer

2) I then tried using CC cleaner, and it still didn't work. I tried using CC cleaner with Explorer terminated via taskmanager, and it windows still persists in recreating thumbs.db

3) I used gpedit.msc and enabled the "turn off the caching of hidden thumbnails files" yet Windows still persists to make them.

4) I tried just straight up deleting the files out of explorer, but it gives me an error message saying "they are open in explorer and cannot be deleted."

:angry:

Is there anything else I can do to prevent thumbnails from being cached in Windows 7 64 Ultimate?

Thanks!
