Microsoft recently added a compatibility block wherein very old unsupported CPUs like Intel's Core 2 Duo, are no longer able to bypass Windows 11 system requirements during version 24H2 setup.
Microsoft confirms that the recent Windows Terminal block experienced by users on older CPUs (without SSE4.2) was not on purpose, and it has urged folks not to indulge in conspiracy theories.
Microsoft is seemingly introducing a new Windows 11 requirement on version 24H2 for older CPUs and it can not be bypassed. A similar change was, perhaps inadvertently, pushed to Visual C++ as well.
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.
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.
Microsoft is reportedly updating the CPU instruction support on Windows 11 with a new "POPCOUNT" instruction, which means systems with very old PCs won't be able to bypass requirements.
