Windows 11 has the anti-feature of not supporting the old processor anymore. Who knows why. Could be anything from simplifying QA and maintenance effort to not being able to (or not willing to) implement a feature on the older platform.
Compared to that, I don't know of a platform Fedora has recently deprecated. Linux usually takes a really long time to deprecate and remove support for old hardware.
criddell is wondering what thing in common Fedora and Win11 had that made switching to either of them preferable to just sticking with Win10, I believe. As in: why not just stay on Win10, unless it was lacking something that Win11 and—apparently, if it was a viable alternative—Fedora have? What was the thing they both had that Win10 did not?
Windows 10 is still supported until 2025 and nobody would be surprised if they extend it two more years. If I were setting up a new machine today, I would probably still install Windows 10. Anything new is an unknown from a security perspective.
Doesn't that imply Windows 11 and Fedora have some required feature that Windows 10 lacks?
