For the average user, with maybe a little bit of IT knowledge but doesn't work in IT, what can we do for ourselves and our families other than go to win 11 eventually?
Unironically, switch to Linux. Mainstream distros like Mint, PopOS or Ubuntu are very friendly for casual users, have GUIs for everything and if something does go wrong, the error messages actually have proper meaning and you'll find tons of resources online as well as people willing to help.
Most stuff nowadays runs in a browser anyway, so here there's no compatibility issues, office is available in Linux through libre office and gaming has come far with steam and proton.
I don't like Canonical either, hence my recommendations for Mint or Pop being listed first. But let's be real, if someone wants to just get away from windows and wants something that works without having to learn much new, this is good enough.
