Finally many unknowns on the problems with VS2005 have been “resolved”. Found this post on the msdn blogs from PeterL a Visual Web Developer Tester http://blogs.msdn.com/petel/archive/2006/07/03/655422.aspx

Lettings us know that cleaning the registry or screwing with the registry is not a good idea. Actually a few tools that claim cleaning the registry is not a good idea, this may prove that. How a tool knows what keys are actually safe to remove?

Please keep sending me emails about your problems with Visual Studio 2005. I have been trying to reproduce them as well as log the results. Hopefully one of these weekends I’ll add them all in a post with possible solutions.

Cheers
