That is very weird and you must have some problem there.
Mine has not restarted even once, and xp used to periodically.
I am with John and Chips, fine tune it a bit so the nonsense notifications go away and use the new features and you’ll get to love it.
My only complaint is that it still has compatibility issues with some other things, but I am sure they will go away.
Boy, I remember the days when the thing used to crash all the time, before XP. There is just no comparison.
