If you use GPOs to enforce baselines, you may find that your enterprise is moving from version 1.1 to version 1.2 of a GPO. Unfortunately for you, version 1.1 linked in a dozen places. Wouldn’t you rather just you search for version 1.1 and replace it with version 1.2? Use Update-GPOLinks.ps1 to do just that. The script not only finds all the original links and updates them to the new version, it also keeps the link order.
