All is good with Windows 7 apart from stuff like this. I am an MS fanboy at the worst of times but they really NEED to rationlise the editions line-up.
Home, Pro, Enhanced is all that is needed at a stretch. Two versions ideally Home & Pro. Yep, that is something they need to carry over from XP.
Continued use of XP is a lot like continued use of DOS as XP came to market. Lets not forget DOS allowed you to completely dedicate all system resources to your single application. Imagine that now (or maybe not...)
