That's a ridiculously implausible and sensationalized rumor. At most, Microsoft may make a NPU a requirement for OEMs to use the Windows 12 logo on new PCs. Actually refusing to support the existing install base of recent and hughly-capable desktops is not at all likely. It would be far more drastic than the hardware deprecations brought by Windows 11, which were already quite controversial (and loosely enforced).
