Windows 7 - I Want Reset WMP 12 Default Size & Position

Hello. I've been looking to Reset the default windows size and position of WMP12 (in the Center of the Screen without Maximizing) the way it is used to be when we launch the WMP12 after a fresh install of Win 7. I know there might be some way to reset it's default size and postion from Regedit (Just like we can reset the Internet Explorer size and position by deleting 1 binary value from HKEY User/Software/Microsoft/Internet Explorer etc. ) but i can't seem to find the exact location and value for this. I've searched on google enough and there were a couple of people who wanted to reset the same thing but unfortunetely other people just posted garbage just like always on other websites and start to ask and talk other things rather than providing the solution and help the user out.

On my dual monitor setup WMP12 starts up where it was closed last. So why don't you just position and size it to where you want it, close and reopen?

I'd stay away from casual poking around in the registry - monsters be there.
