Administrative Template File (ADM) Format

The Group Policy Object Editor can obtain registry-based policy settings from an administrative template (.adm) file. An .adm file defines the property page the Group Policy Object Editor will display to allow the administrator to manage its settings. The file also indicates the registry location where the settings are stored.

If your application offers management capabilities through .adm files, it must store these policy settings under one of the following registry keys:

  • User-specific:

    HKEY_CURRENT_USER\Software\Policies

    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies

  • Computer-specific:

    HKEY_LOCAL_MACHINE\Software\Policies

    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies

For more information, see the following elements:

The following is a sample .adm file.
