Windows 7: Wallpaper automatically reverts to one picture.

Hello, all. For a while now I have had the issue of a desktop wallpaper that seems to want to revert to an old file every time I restart/turn off my computer. As far as I know, this file only exists when it is a "transcotedwallpaper", and it is not backed up. I have tried the regedit solution of "NoChangingWallpaper", I have turned off system restore and deleted all restore points, and I have deleted the original file. I've now undid the regedit changes I made (safely, I can assure you), and am at square one. I have no idea what could be causing this to happen, but I would prefer to find a concrete solution to cleaning up whatever corruption this may be rather than a work-around.

One thing I have noticed is that when I start up, it will show my intended background before reverting to the old file. However, it never changes the color-scheme of my taskbar, only the wallpaper itself. In addition to this, I will have my desktop icons set to be hidden, but it will turn those back on when it replaces the desktop background with the old file.

Here are some of the things I tried:
