I had to briefly go back to Windows and I just couldn't understand how anyone serious can run an OS that just decides to reboot itself in the middle of the night.
For most users, they don't even notice that it rebooted, because their apps were relaunched and put back in place. It's (ironically) the people who run Linux who notice, because they probably have their Windows machine full of FOSS ports from Linux that don't restore on relaunch.
Well, it just so happened that I did notice the reboot last night, when it just cut off my moving of 500GB of files to one backup HDD and the defrag that was running on another. Neither of those just relaunched themselves.
Did you notice any warnings that there would be a reboot while you were setting up the file copy or defrag? How many hours, cumulative, had you spent in Windows in the week leading up to this reboot? I think the answers will reveal that my point is being illuminated nicely, and I thank you in advance for the assistance in this matter.
Just install Reboot-Blocker. Or equivalently, define a Scheduled Task that rotates your “working hours” every hour, so that it always matches the current time. Yes it’s annoying to have to do that and that there isn’t a simple switch anymore like there used to be, but at least it’s defeatable.
Apple has decided to take this paternal route as well, and it's quite frustrating. The good news is if you use the Pro version of Windows, you can disable that. Still crazy you can't fully disable it using standard setting on the consumer version, of course.
The (only) people who pay for Windows are corporate managers. Therefore, the main purpose of Windows is to make corporate managers happy. Corporate managers want updates to install promptly, so they can tick their ISO compliance box saying "no insecure software running here". They couldn't care less about an annoying experience or slightly reduced productivity for their underlings. Therefore, Windows succeeds at its main purpose.
