It was simply arrogance and stupid: How would they know when the user is going to be inactive and the computer can be restarted? A couple of years ago, one of my colleague's computer was rebooted for updating in the middle of a important presentation to his boss and the time needed to complete was over two hours. Now they allow the user to specify an active windows which is a little bit less stupid but my question still stands. Even the user cannot tell exactly when she/he would not be using the computer but for sure M$ product managers decided that they KNOW. And the more funny thing is that the benefit they can get by doing that is very limited or even NIL as how could they ever know what the user would set that that window to and whether the user isn't going to shutdown/put it to sleep/hibernate before inactive windows and power it again later?
