I was just about to blow away my last set of Virtual Server images and spin up a new set from some sysprep’d images I setup just for this purpose when I remembered someone mentioning the Uninstall tool Microsoft released a couple of weeks ago. This tool takes the pain out of having to remove all the old bits of VSTS & SQL 2005 you may have previously installed as a beta or release candidate.

If this tool sounds useful for you, it can be downloaded from Microsoft here  (315kb). This page also details the manual steps which (fortunately) you should never need to do again.
