Before you can create ADMX-based settings, you must import the ADMX templates containing the policies that you want to configure.
Note: You can use ADMX templates that you import for both user environment settings and computer environment settings. The same collection of imported templates is used for both.
Procedure
What to do next
Remove the templates that contain only unsupported settings or policies.
Note: You can remove the templates if they are not used by any settings definition.
