Re: new hardware requirements
Digging I've come across some information which suggests mandatory support for "Virtualization Based Security" and/or HVIC is the root cause of the Hardware requirements and why MS really chose to stick an "11" tag on the new build. It's available in 10, but the mandatory support requirement isn't?
If they'd been a bit more upfront might have helped? My suspicion is that it isn't on by default for upgrades (not on my insider build) - but could well be for OEM shipped installs?
There are subtle differences in CPU specs between the i7-7820HQ and the i5-7200s I have (with TPM 2.0) which may explain why one can run W11 and the other can't?
Also may explain why support for VMs is a bit vague - nested VM support?
