These cmdlets wrap the functionality around managing Group Policy Objects available within the GPMC, into handy PowerShell cmdlets. This version comes with 9 cmdlets for performing GPO management tasks like creating and deleting GPOs, linking them to sites, domains and OUs, modifying GPO security and backing up and restoring GPOs.
This free set of cmdlets is a great compliment to our commercial GPExpert Scripting Toolkit for PowerShell.
