AppRocket

If you have ever heard of Quicksilver for MacOSX, this is basically the twin for Windows by CandyLabs. AppRocket is a wonderful way to quicklaunch applications. For Windows 2000, 20003, XP & .NET.
The download is a 30 day trial and a one-time fee of $18 afterwards. Perhaps not free, but definitely one of the most useful utilities you will ever come across for Windows.
The tutorial for setting up AppRocket can be found here.
