on C-Drive the Folder c:\AvtiveAdministrator\GPOHistory is growing over 80 GB
Even with only a health license and unlicensed GPO management tools.
Upgrade to Active Administrator 8.7.1
Any unlicensed components, including the GPO module, will automatically be disabled in the server. This means the GPO backups will no longer build up once the customer is on 8.7.1 with the AD Health license.
After this, it will be safe to simply delete the folder containing the GPOHistory backups.
