Most of the policy settings that can be configured on a stand-alone computer are stored in Administrative Templates. These are .adm files located in the %systemroot%\System32\Policies\adm\ folder and define options available in the Group Policy console. The settings available through administrative templates are also known as registry-based policy settings as they change or add a key in the local registry. The administrative template WMPlayer.adm contains policy settings for customizing and controlling Windows Media Player 9 settings.
