First, you can always restore ANY GPO if you have a full GPO backup.  If you have a GPO backup, then follow these steps: Here’s our video on it..  https://kb.policypak.com/kb/article/938-10-integration-with-group-policy-basics-installation-backup-restore-and-reporting/

However, if you do not have a full GPO backup, but only have an Active Directory backup you can still use this as a restore point.
The way to do this is to find the file that will be in the backup, like this.
Note the path, in this case, LPM is about PolicyPak Least Privilege Manager.

Then you can use this file from the backup, and perform an “Import from XML” like this.

Note this might not work for all types of PolicyPak items, like PolicyPak Application Settings Manager; but should work in most cases.
