The fact that pressing spacebar during boot can accidentally upgrade your OS tells you everything about Microsoft's current priorities.
I accidentally "upgraded" a test machine by hitting Enter during a BIOS update prompt. The machine rebooted into Windows 11 setup, which then took 45 minutes and required a Microsoft account (or knowledge of the OOBE\BYPASSNRO trick).

If you want to block the upgrade permanently:
Or just install Linux and never worry about it again.
