> minimum processor & TPM requirements in Windows 11 have been shown to be entirely arbitrary.

I am curious who thinks they managed to show this. My understanding was that the minimum processor requirement was born out of hardware feature requirements.

I know Virtualisation Based Security is on by default in Win11, and Intel processors older than 7th Gen don't have Mode-Based-Execution-Control, so they emulate it at a hefty penalty (they call it Restricted User Mode).
