I am taking a look at it but these are API's that I am not familiar with (and I'm not sure we have any Windows experts who can review, other than Microsoft folk themselves). My main concern would be compatibility - ensuring earlier Windows versions continue to behave the same, but also the impact on applications already running on Windows 11 or Server 2022 which may suddenly get an increase in the number of available processors. We might need a product flag to opt-in to this new behaviour, or at least a diagnostic flag to allow users to opt-out.

Thanks @dholmes-ora. I will add a product flag to opt-in to this new functionality.
