I haven't actually seen a Win10 automatic upgrade happen as its blocked on all of mine (using Never10) but plenty of customers retail and business have reported it obviously (and quite a lot have been fine, but people seem to lose audio drivers a lot - or at least Win10 seems to default the audio output to headphones instead of speakers). But one of my customers came in the other day to find it was in the process of upgrading and was sat at a login page, or at least a dialog that said "Confirm your login/username" with a "This is not me" link below. Well they clicked "this is not me" and the upgrade backed out and rebooted back to 7.
So I havent got the exact text or screenshots, but it seems - on 7Pro at least, this is cheat option to avoid some messing about - certainly it took a few seconds rather than many minutes/hours.
