Personally im a bit mixed about this. Loosing support for things like old hardware is bad. Still windows 7 support is dropped my Microsoft it's self. Together with 8.1 on 2020.

Microsoft is offering free upgrades to windows 10 and now windows 11. (Wondering how bad it's going to be when they cut win10 support)

So if you have an retro gaming pc it's sould be better be offline. So as the games etc.

It's probably costing the company money. And in the decline we are in they probably cut cost. Probably a few dusty servers and some space may even a full building they pay rent for.
