Windows 10 21H2 and Windows 11 21H2 both show up as "2009" release

I'm not real sure where to post this, so will try here.   I have noticed that for both Windows 10 - 21H2 and Windows 11 - 21H2, the "ReleaseID" value in the Registry is incorrectly shown as "2009"....

DisplayVersion is also 21H2 for both (Server 2022 too)
you should rely on CurrentBuild or CurrentBuildNumber
22000 and higher = Windows 11
21350 and lower = Windows 10

all "Windows 10" in the registry are left for Windows 11 probably for compatibility

      "2009" with Systemtype "OSType64BitX64".

      What does this mean?
