My wife was working from home last month for the first time in forever and that's when Windows 10 Home decided to upgrade to the Anniversary update. Try and I might, I could not seem to find a way to stop this. It took well over an hour, in the middle of the day, to install Windows and kept her from working.
That's one of the most user hostile things I've ever seen in a software product.
Ironically, after the Anniversary update we could at least set the working hours but it's still limited to a 12 hour block. Is it really too much to ask to only allow updates/reboots from 1:00am to 6:00am?!?
I'd like to think if any of this happened to the CEO of Microsoft, this crap would get fixed right away.
