Good point, I would not recommend Win 10 for critical system, or purchase the extension support from Microsoft (yes, they have it).

To me, I am good with an OS without support, I'd rather these developers and PMs never touch the Win 10 base code anymore, and let it be there like this. (for small issues, I can fix it, for critical issues, MS will release patches for free).

My wife used a Win11 laptop, and her Win11 wasted me tons of time troubleshooting. my gut tells that the then Win10 developers coding skill is way better than the Win11. They have a hand of good card but play like a mess.
