I hadn't noticed the icon until I read this thread but it was there and I've reserved my copy for this machine.
I shall certainly give it a fair crack of the whip, let's hope it's a goodie and they've learnt from their last 'upgrade'.
As I've mentioned before, I will back up my current Win 7 install using Acronis True Image then if I'm not happy with the newest Microsoft offering I can soon go back to things as they were.
Looks like a win-win situation to me though not too happy if having to have automatic updates is a proviso. We shall see.
Also got to think about all those saved games that are scattered all over the place on drive C.
