Vista Start Menu for XP with ViStart
 

Windows XP only: Freeware app ViStart brings the functionality of the Windows Vista Start Menu to Windows XP. ViStart not only offers the Vista style eye-candy and transparency for XP, but also the highly regarded quick search function of Vista. ViStart was designed to be included in the Vista Transformation Pack, however you can grab a stand alone version if you would prefer not to install the entire pack. ViStart is lightweight, skinnable, and another great feature of Windows Vista brought to XP. ViStart is a free download for Windows XP only.

Once more Vista feature that's useful that I get to use on XP :) the Start Menu Quick Search is very nifty

Does this app allow you to search both programs and OS settings menus on XP?

for what I've used it now, identical to Vista, quick search to all shortcuts and commands in the start menu.
