Just got an email that says Windows Server 2022 is now available (only got it 8 days late), I may play with this in XCP-NG and see what’s what. looks like you need to be a member of the Insider Program, which I should be, but still not allowed to download it.
I’m wondering if it will require secure boot which is still a small problem on XCP-NG after the January Security updates.
 guess I had to register again???
