The How-To Geek has posted instructions for creating your admin panel. I followed his Vista example on my XP box, easily. There were a couple of minor differences , but it is a <ahem> snap.
Why? As the author says, navigating the Windows menu for individual utilities like disk management, user management, services, and so on is inconvenient. Combining the utilities I use most often into one admin panel is a great productivity tip. Thanks, How-To Geek (and Steve).
 The task scheduler isn’t an mmc snap in in XP.
