Congratulations. That means that your machine was not infected by a beta version of Visual Studio. Rather a notorious problem with VS Beta and RC editions, the uninstaller is always the last thing they get right.
What you are trying to do has nothing to do with the problem you are trying to solve.
You'll want to read this feedback article, posted by a VS user that also complained about missing User Type settings in the dialog. No boo or bah back from the original poster of the article, sounds like devenv /setup
took care of the problem.
