Similar to the Windows 11 system requirements bypass method, a tech enthusiast managed to run Windows 10 22H2 on an old unsupported CPU using a trick, though it won't work for everyone out there.
The first Windows 11 24H2 Insider build was eventful as it brought many new features and improvements while also confirming a shift in CPU ISA support. The next one builds on top of it.
There has been an interesting trick, a single command, that allows unsupported CPUs to bypass Windows 11's system requirements check during setup. That has seemingly stopped working on very old chips.
