Windows XP Start Menu Customization
Here is the Advanced Options dialog for "Customize" for the XP Start Menu. There's a lot of options here, but it's easy to understand. It takes 3 clicks to get to this menu, Right click Start, choose Customize, and click on Advanced Tab. Most end-users probably wouldn't mess with most of these settings, it's the type of stuff that would usually be rolled out with System Policy in a large organization.
