ADM (old style Group Policy) to ADMX (Vista style Group Policy) migrator - can also be used to create and edit new policies

ADMX files are 'the new way' to do Group Policies in Vista and Longhorn. Thankfully a large part of the group policy engine was reworked and rewritten for Vista and Longhorn. You can now create a centrally located repository inside of SYSVOL to store all the newer style policies.

If you want to convert older style ADM files to ADMX, or create new ones within a MMC session, download this program here.
