Good call! Too late for me now so, especially since the majority of my Steam library is running just fine under Linux. Maybe for some online stuff, Teams for potential home schooling and so. The fact that local accounts are hidden sucks in itself so. I will keep Windows on my private laptop so, just in case. Not that I am going to upgrade to Win 11 so.
Better switch your wifi to metered connection then, like recommended upthread. Prevents automatic updates and being upgraded involuntarily (hopefully).
