I agree Tony. I think they're trying to be far too unobtrusive, but it's failing. I'm more and more convinced that those 100% disk usage problems I was seeing were the result of an update.

Doug, your report of "update and shut down" is something I actually haven't seen yet in Windows 10. Interesting.

I have noticed that when Microsoft wants to force a restart, they're much less obtrusive about that now, too. You no longer get that bright box at the bottom right, letting you delay 10 minutes or 4 hours or whatever. You do get a small black notification that makes you go to a little more effort to delay a restart.
