Hi,
So this is what I did today. I downloaded the V2 of Windows 10, 21H2 and then I just added the ADMX/ADML from the Windows 11 package where the Windows 11 ones had newer settings I wanted.
I opened both in Notepad++ and did a "Compare".
I used the grid above to identify any policies I would use like the Chat one for Taskbar and the Register DNS Securely one.
I just copied over the ones that I wanted like DNSClient.admx/adml and the Taskbar.admx/adml that had the newer settings but the older dates.
So I created a folder of the best of each and I used that on my Servers.
They worked just fine and they open fine and I can set the settings and they apply to both our Windows 10 and Windows 11 computers as well as our older Windows 7 ones (Yes we have the extended license for some Hospital Applications that are very expensive)
