SUMMARY
Visual Studio .NET Beta and Release Candidate versions may not be completely removed because of problems in the removal programs. This article describes how to manually remove all traces of these versions. You must also use the Add/Remove Programs tool in Control Panel to remove all managed programs that are installed on the computer, no matter which version was used to develop the managed programs.

Note that it is a good idea to start over with a &quot;clean&quot; installation of Microsoft Windows, especially in mission-critical development or build environments.
