Hi @Fahrid F ,
The administrative templates you've linked also apply & work for Windows Server 2016, if you want the latest available administrative templates you can find them over here:
Administrative Templates (.admx) for Windows 10 May 2021 Update (21H1)
If you use a central store to manage your administrative templates (.admx) you can follow the steps over here:
The Central Store

If you don't use a central store, you can follow the steps over here:
