When I open Media Center and go to Pictures + Video there is a preview picture for the Desktop that I do not want. I have searched my whole computer for .bmp, .jpg, .gif and .ico files and that specific picture is nowhere to be found. How can that picture preview be there if the picture is not on my hard drive?

Vista Home Premium 64bit

Problem solved.

Went to the desktop folder under the Administrator. Tools - Folder Options - View. Unchecked "Hide Protected Operating System Files". Then the picture showed up. It was slightly grayed out, but I was able to right click and delete it. Actually there were two of them one small .jpg and one larger .jpg named Folder.jpg. I have no idea how they got there or why they were hidden images. I imagine that they were installed by a rogue program I installed.
