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"....
Keith_Hemmelman we had the same question a while ago.
The ReleaseID regkey is deprecated.
Windows 10 21H1 reports ReleaseID 2009 | Born's Tech and Windows World (borncity.com)
Instead you can use the DisplayVersion regkey from HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
Otherwise in Windows 11 this key is showing 21H2. I did not find an exact reason for this.
If anyone has a clue, please share, that would be great.
About the buildnumbers for Windows 11 this link can clear this out.
Windows 11 build ver is still 10.0.22000.194 - Microsoft Q&A
