It’s a little different for each component.
PolicyPak Application Manager
PolicyPak Admin Templates Manager
PolicyPak Admin Templates Manager policies don’t need any “revert” item set for normal ADMX entries that ship in the box from Microsoft
Revert when no longer applies should just happen automatically.
PolicyPak Security Settings Manager
Policies don’t need any “revert” flag set. Items that CAN revert will. Some security setting cannot revert by their nature once they are set. You should test out revert on security settings before major deployment when possible.
PolicyPak Preferences Manager
When using PolicyPak Preferences Manager to deploy Group Policy Preferences items, settings DO need to be specified to revert, or they will not.
Here’s an example of how to specify to “Remove the item when it is no longer applied.”
This flag must be set or PolicyPak cannot revert the item when the policy no longer applies
