Very likely the good MS guys will noti[fy] you before upgrading your system, but what if they don't
You have put your finger RIGHT upon the fundamental problem.
I will point out (again) that systems are by default set to automatically install updates. How many have changed the defaults?
A grand majority of folks still implicitly trust Microsoft to do right by them. As well they should - Microsoft has delivered a decent operating system in the past, and for not too much money.
So... The real question that remains to be answered is, as you have aptly put it:
party-pop or a man-killing device
Microsoft seems just arrogant enough lately that it might not be the former.
