> windows 10 … won't let the user decide when to reboot and install updates
This isn't actually true; there's a setting in the control panel to tell it when to reboot and install updates.
That said, Windows 10 will reboot to install those updates, and then, next time you log in, will make you wait several minutes while it 'finishes installing updates'. It also does so in what is intended to be a user-friendly matter, but which comes across as creepy and menacing. The first time it happened, I logged in to see a screen that said
'Hello'
Then:
'We've made some changes to your computer' (or similar unsettling language)
And then, as if they realized at this point how menacingly they were coming across:
'Your files are all where you left them'
I was 95% sure that I'd been malwared and someone had encrypted all my stuff for ransom. I actually had a moment of panic, wondering what they would have had access to from that machine.
> This is why people buy overpriced stuff (like Apple!).
I would argue that if the frustration-free approach that Apple tends to embody best appeals to you, then it's not 'overpriced', it's just more highly priced.
