Hard to use how? What exactly is it you find so hard to use? The Metro Start screen (despite ugly) is very straight forward and that's pretty much the only change that has been made, control panel wise, file searching wise, software installing wise is exactly the same as Windows 7, and the only difference I see between 7 and XP, is the look and the UAC feature.
How is it hard? What about it is so confusing? I don't get your point.
