I recently purchased Windows 8 Pro and installed it with no problems. However, I am only able to change my wallpaper to either a solid color, or the default flowers picture. I can't use a custom image or one of the built-in images.
I can modify the theme's color, sounds, and screen saver, but when I try to change the background, it will automatically revert to the "Windows" theme. If I attempt to choose another built-in theme such as "Earth" or "Flowers", it will also revert to the "Windows" theme.
I found this thread after a quick Google search which tells me to delete a file called TranscodedWallpaper, but, after doing that, when I try to change the theme or background, it'll once again revert to the "Windows" theme and then the file I just deleted gets recreated.
This seems like a trivial problem, but nothing that I've tried has been successful. Sure, the daisies wallpaper is cute and all, but I'm more of an outer space guy.

However, choosing a solid color does:
