System.adm, Inetres.adm, Wmplayer.adm, and Conf.adm use the four reserved Group Policy registry areas. For the locations of these areas, see Windows NT 4.0 system policies

Visibility of System Policy settings in the Group Policy console

When you add an .adm file to Group Policy, as described in To add or remove an Administrative Template (.adm file), by default only the settings that are contained in the genuine Group Policy trees (the trees that correspond to the reserved Group Policy registry areas) are visible in the console.

If you want to change this default behavior and make not only Group Policy settings but also the older-style System Policy settings visible, see To filter the view provided by Administrative Templates Clear the Only show policy settings that can be fully managed check box, as described in that procedure. Your ability to clear this check box in the Filtering dialog box is subject to the Group Policy setting "Enforce Show Policies Only."

When you make System Policy settings appear in a Group Policy console, the icons for these settings are colored red. The icons for true Group Policy settings are colored blue.


It is highly recommended that you not use System Policy-type .adm files when you manage Windows XP or Windows 2000 clients, because this can lead to undesirably persistent registry settings. For more information, see Migration issues
