We raised our forest functional level and domain functional level to Windows Server 2008 over a year ago.
We have been performing a growing number of tasks through group policy but seem limited. In particular Computer Configuration - Policies - Windows Settings - Security Settings - Registry. I see on-line about a registry wizard which we do not have the option. I've seen ways of updating adm, admx files for Administrative Templates but its under a different section of the group policy management editor.
We are running Windows 2008 Standard on all our domain controllers, not 2008 R2.
