But not any less usable.
I tried Windows 11 on Compal FL90, a 16 year old laptop. It ran fine, better than Windows 10. But it didn't meet the requirements to allow installation, even though it worked just fine. So some 5 year old computer that doesn't meet requirements for whatever reason would also be just fine. And I don't think people will bother with making hybrid installer just to get Windows 11 running.
Just for fun, this is how fast it could boot up with Windows 8.1:
Link for compatibility
8.1 actually outperformed both Windows XP and Windows Vista this laptop was made for.
Anyway, even with Windows 11, it was still pretty fast. I didn't try any better games, but Asphalt 8 and Asphalt 9 ran on it nicely. It's just to say that old computer doesn't mean it's garbage.
