If you want people to accept forced updates, just send the security fixes. Don't change the UI and don't mess with the users preferences, especially concerning privacy.
Honestly, I've never heard anyone complain apart from tech people. Long reboots are annoying but overall, Windows 10 is pretty well accepted by every non-technical person I know.
Oh, the non-tech people hate it too, but what can they do? They have literally zero choice in the matter.
That's the thing with tech, and that's why I consider all arguments that "people voted with their wallets" to be bullshit in this space. Most users don't understand how computers work. They don't have mental models to recognize how things should work. They have no choice but to accept whatever they're being given.
Devices around them getting less ergonomic, slower, and more flashy UIs? "There are smart people building this magic, they must know what they're doing!". Their computers slowing down to the point of uselessness in the span of a year? "It must be these viruses!". Techies complain because techies understand it's all greed and laziness, and that same technology is capable of being much better than it is.
I mean, ask your parents whether they like their operating system. I'll bet their answer will be a resounding "no", and you may get an earful about their general frustrations with technology.
One notable moment where the dissatisfaction of masses was voiced in unison was the forced Windows 8 to Windows 10 upgrade. You didn't have to have any sophisticated mental model there to recognize you're being made to do something bad for you against your will.
A friend of mine uses his PC only in the weekends (he uses the company's PC during the week) and hates Windows because every time it takes hours to download and install updates over his slow ADSL (I think there is no fast Internet there.) He has to remember to turn the PC on in the morning to use it in the afternoon. If he forgets, next weekend. Of course he could turn it on Friday night but the user experience is still really bad.
What are you talking about? Non-tech people complain all the time about it. Updates deciding to run right before you have to give a critical presentation is a meme at this point.
All this "well, users are stupid so it is ok to treat them like garbage" nonsense is part of the reason I've come to fucking hate IT. I wish all of you who think that way would go away.
Because non-technical people probably don't even know they have a choice in the matter. Macs are too expensive and they've probably never heard of Linux.
