To note: Windows 10 is still supported and will be up to 2025. And when that date arrives, Microsoft has a history of patching out of support Operating Systems. Mostly because they have large enterprise contracts which last longer than the EOL of their OS.

Also Microsoft provides an official guide on how to install Windows 11 on older hardware. My neighbor has Windows 11 on his 10 year old laptop running an i7 2500 and it's butter smooth.
