Quick quesition regarding my desktop

[blueboles]

I'm running XP home and my desktop has gone away. I have a pretty background, but have to run all my programs through task mangager. Does anyone here know the path to the display settings. If that doesn't make sense I'm talking about when you say want to change your background or screensaver you would click start, then programs, acessories, settings, display. You know that whole deal.
I need to know the actual path that takes so I can do it from the folders. You know C:, programs, what ever... what ever.
I hope y'all can help.
thanks!
