stwert, if you were using a mac you could just change it without having to use hacks :p
i downloaded something called display fusion, it's free (the paid one has more features though)

i too usually have renders as my backgrounds but a few weeks ago i changed it to other pictures after installing windows 7

probably can't see it but those folders and documents on my desktop are all labeled untitled something... because i usually just put tempory thigns onto the desktop or things i dont know where to put onto the desktop

I use this one when working with multi-monitor setups. http://www.realtimesoft.com/ultramon/
