The issue here (as mentioned by Wayne) is that Win 11 is the current version of Windoze and support for Win 10 is ending.
Many older computers cannot be easily upgraded to Win 11. Apparently there are hacks that might work to allow installation of Win 11 on machines that Microsoft says are not supported. Unfortunately, hacks can cause other issues. Anyway, most people probably don't want to spend time researching and implementing hacks.
Supported means that Microsoft provides updates. Without updates, you won't get any security patches or other fixes; your computer still works. Win 7 users will have not had any updates for a long time but it still works for them.
Writing computer viruses is not easy and even without current updates, the operating systems are pretty good at detecting them. So, the bad guys find that it's easier to use social engineering instead. They trick users into giving up their banking info. This is a big issue with artificial intelligence. The tricksters will be able to easily fool more people.
Some people like Win 11. If you have a computer that does not support Win 11, buy a new one.
If you don't care about Win 11, you can stick with Win 10 (or Win 7 like Otto) as long as you want. Presumably the hackers are now looking for Win 11 vulnerabilities.
I use Linux, so I don't care either way! There is a thread in this forum on Linux if you are interested.
