I was trying out the themes that you can download from Display Properties that you can get online. So I tried maybe 10 themes and chose one that I liked and Win 7 is saving all the jpgs from all the themes after I deleted the themes. The theme pictures are hidden in this folder.

C:\Users\User\AppData\local\Microsoft\windows\themes\Tale of Cities(example)\DesktopBackround

Now Win 7 will not let me delete them separately. Says I need permission from Trusted platform crap.

How do you dump all these jpegs?

KRAP!
