I read today that Microsoft has shipped the updated Desktop Optimization Pack for Software Assurance customers that includes the DesktopStandard GPOVault product, which MS is calling "Advanced Group Policy Management". For those who don’t know, GPOVault is a Group Policy change control product that integrates into GPMC to let you do check-in and check-out of Group Policy changes before deploying them into production. If you are a Software Assurance customer, you get it as part of the DOP.
If not, well, sorry
