Hiya, Are these any different from the ones found under %WINDIR%\PolicyDefinitions on a Windows 8.1 Machine?
I'm unable to check at the moment, but I think this download contains the ADMXs from both Windows 8.1 and 2012 R2 'PolicyDefinitions' folders.
The Server 2012 R2 and 8.1 files should be identical.
If anyone wants to know how to easily import these files, have a look here
As a recommendation, import them on your PDC and it'll automatically replicate out to all other DCs.
