Microsoft Windows Vista® and Windows Server 2008 introduce a new format for displaying registry-based policy settings.Registry-based policy settings (located under the Administrative Templates category in the Group Policy Object Editor) are defined using a standards-based, XML file format known as ADMX files.There isn't any strict rule for how this works - it depends on the product and how that specific policy is written.
Also, how does this work for templates for other MSFT products, such as IE or Office? That is the case with some other products, like MS Office.
In addition to the above search, you can also search for a Microsoft Excel spreadsheet which highlights the changes in GPO’s for that platform, for example search for the following phrase: Once you’ve found the corresponding templates for the version of Windows 10 you want to support (for example here are the ADMX templates for Windows 10 1511) then download the MSI (or copy it) to the desktop of your source computer.
Double click on it to start the installation (extraction) accept the EULA and then let it extract the files to the default location which is something like C:\Program Files (x86)\Microsoft Group Policy\Windows 10 Version 1511\ close the wizard when done.
We have a 2x Server 2003 DC's, and manage group policy using the administrative tools on a couple Windows 7 workstations.
We've just started using the domain central store to ensure that we're all seeing the same settings.
