I can't imagine how building is freezing your computer when using the command-line isn't; all VS does is call cl, link and mt in that order, you can procmon it and watch it happen. The Intellisense thing, on the other hand, is the most ridiculous thing I've ever seen - the official Microsoft solution is to delete the Intellisense database and restart VS, apparently it "gets corrupted over time" and they don't feel the need to look into it
