But I have not had a single unexpected reboot on my win10 install. It's because I always update at the next time of convinience. Updating is required maintenance of any software system and you can't afford to ignore it. I also see some consequences of questionable behavior blamed on windows. You should never have hours worth of unsaved work open. NEVER. Don't blame windows or whatever, just dont ever do that or at least bear your shame quietly.
Also, please for the love of god, stop lobbying for OSes to faithfully restore your open apps on reboot. The only way to solve a lot of problems is to be able to really reset the state of everything which is not worth trading for your ability to better compulisvely hoard chrome tabs. That shit is not healthy btw.
Finally, reboots are necessary on all major operating systems, even linux. Remember Windows user used to be free to apply updates when they wanted but you, yes you, MS hater of yesteryear kept blaming MS for the large number of unpatched and therefore insecure Windows systems. So they don't give users the freedom to postpone indefinitely and of course it's also not right. So what can they do?
