Open display control panel as another user?

Hey, Can someone tell me how to run the display control panel as another user?

I have tried runas but I cant use desk.cpl because runas only allows applications.

Also - If you add a noprofile arguement will that bypass restrictions on that account? Eg;-

User 1 is not allowed to change his wallpaper. If user2 (who is allowed to change his wallpaper) ran the display control panel as user1 using a /noprofile arguement would the changes be saved as user1 when he logged on again?

Thanks.
