I want to change my desktop, but my computer wont let me because I accidently made my desktop a theme and when I try to get rid of the theme, it wont let, me so I cant change my background unless I make a new theme and I dont know how to make themes, nor do I want to, how do I get rid of the theme?

Moved to Technology. Just kidding, someone else move it.

whitney you should be able to move this yourself. can you not?

try to find it in ur system and delete it. check my computer>c drive/hard drive>windows>resources. see if it's in there and try to delete it that way. this is the only way that i know how to find it and delete it.
also, might i suggest checking out deviantart.com for some cool themes. some come with instructions on how to install it.
