I'm on Win11 for 1.5 year or so (Win11 Insider Beta channel) and before was on Win10 Beta/Dev channels - so what I remember so far, I was warned multiple times, suggested to pick a time and only after user (me) not shown any cooperation, system was forcibly rebooted, which for consumer grade (I have Pro version) edition is fine, from my PoV. I don't want [my] system and systems around me be a part of botnets like Linux boxes of all sorts.

This needs application support, by this broad definition all operating systems "saves state and comes back right where you started on a security update reboot".
