I am using version 21H2 Build 22000.318 as a Guest VM in Parallels Desktop, running on Mac Silicon, thank you
I switched through UUPDUMP months ago to the "commercial" release (meaning it wasn't in either of the beta threads through the Windows Insider preview) and I am up to 21H2 also but Build 22000.675. Not much different from where you are. Getting all the security updates and from what it seems the usual MS updates also. Used a Windows 11 key to authenticate it.
