The problem with those conclusions is that not one of those hardware functions can not be emulated in software and just as securely. The only down side to doing it all in software is a somewhat higher system resource cost. This cost is minimal on a CPU with 4 or more cores.From what I've read, the reason why Microsoft is requiring newer CPUs is because of a technical reason. Starting with Windows 10, Microsoft included something called Virtualization-Based Security or VBS to isolate parts of system memory from the rest of the system. VBS includes an optional feature called Hypervisor-protected code integrity, or HVCI. HVCI can be enabled on any Windows 10 PC that doesn't have driver incompatibility issues, but older computers will incur a significant performance penalty because their processors don't support mode-based execution control, or MBEC. PCs without processors that support MBEC rely on software emulation called "Restricted User Mode," which does get you the security benefits but affects performance more (sometimes as much as 40% by some users).
Going forth, the optional security features of Windows 10 will be mandatory under Windows 11.

So effectively microsoft is once again blatantly lying in order to justify their position. This only re-enforces the idea that this is a money and control grab, little more.
