Windows Explorer Registry Problem? Un-closeable Windows Explorer

Hello again.

Apparently I’m an ***** and ran Fix-It Utilities 4.0 and did something terribly wrong. After the program ran I think I may have had another application running and it caused a weird problem. Now the desktop background has turned to a big empty Windows Explorer window(?). I can’t for the life of me figure out a way to turn it off, it is “on top” of my normal background. When I unhide my icons most of the background comes back but the Windows Explorer “Bar” is still on the left hand side. I assume it is some kind of registry problem with Explorer but I can’t find it and I have tried a couple registry apps.. If someone knows how to fix this, I would truly appreciate some pointers. Thanks for any and all help, Scott

P.S. I can send pictures if it would be of any help to diagnose the problem.
