So i guess no one liked my idea? I mean even XP apps should beable to run in compatibility mode and you can make them do that automatically without manually selecting it.
it also wouldnt be hard to make W7 look and function like XP. You could even change the boot screen to match it and chances are, they wouldn't be the wiser.
But of course if those apps still don't function and they don't like the idea of Virtualization then just tell them they are SOL.
You're talking about people who have been using XP for many years. The differences would be easy to spot, even if you made efforts to skin.
