I have a few machines which lack a supported CPU. There's CPU's only 6 years old which aren't supported. There may be some newer ones even (I didn't bother to look).

If it was 2000 - it'd be like, "OK boss, you gotta upgrade that old dog of a CPU", but software bloat really hasn't kept up with CPU performance. I've got an i3 which is serviceable enough from 2014. Is it going to be able to keep up with modern SQL Server and Teams and VSCode and all that? Probably not all at once. But totally fine for basic computing.
