The task manager is something I use to find the app that's misbehaving (usually Firefox) and kill it; I can't imagine much relevant improvement, unless it somehow allows me to do this faster. It would have to be faster than "control-shift-escape -> [start typing name of offending app until it's selected] -> alt-E -> enter -> escape" -- maybe using the "control" modifier instead of "alt" would be an improvement, or maybe assuming I'm only going to kill one process and exiting the task manager automatically after killing the app.

Other than that, I've got the login screen bypassed on boot and file copying has not been a problem for me; I don't see any value here.

I don't need to put up with any of that other stuff; I'm happy with Win 7 the way it is.
