In the July 29 to August 12th Hot-fix release for Windows 6/7 there have been a number of Group Policy related hotfixes released. As far as I can tell none of these hotfixes are listed as being in Windows 7 Service Pack 1 that is currently in beta (see The complete list of Group Policy Hotfix’s in Windows 7/2008 R2 Service Pack 1) so if you are experiencing any of the above hotfixes it will be some time before you will be able to deploy them as part of a service pack.
