YOu can use internet exporer, right click on it and choose run as (mnake sure you dont do this on the desktop shortcut IE but on the one in quick launch or start menu.

ONce it is running under Admin you can type control panel in the address abr this then runs Control panel and all its applets under admin privelege.

There is various documentation stating that using the runas command with control.exe works however i have enver managed to get thsi working

using IE worka ll the time for me
