You have to copy the files to:
%SYSTEMROOT%\PolicyDefinitions

Or if you are using a CentralStore, just copy these files to:
\\DOMAIN-FQDN\SYSVOL\DOMAIN-FQDN\policies\PolicyDefinitions

Update ADMX files for Windows 10 1709 in your Central Store

Download and install Windows_10_Fall_Creators_Update_1709_ADMX.msi

https://www.microsoft.com/en-US/download/confirmation.aspx?id=56121

All admx and adml files will be extracted to “C:\Program Files (x86)\Microsoft Group Policy\Windows 10 Fall Creators Update (1709)\PolicyDefinitions”.

Now backup your actual Central Store folder:

 \\yourdomain.com\SYSVOL\yourdomain.com\Policies\PolicyDefinitions 

and after that, copy and replace the extracted ADMX and ADML files to the PolicyDefinitions folder.

For some reasons 5 amdl files are not in the other language folders... you have to copy the following adml files from en-us to all other folders, to avoid errors.

GroupPolicy-Server.adml
GroupPolicyPreferences.adml
MMCSnapIns2.adml
TerminalServer-Server.adml
WindowsServer.adml

After replication finished, you can administrate the new features of Win10 on all DCs.
