Microsoft have recently released a couple of hotfixes relating to Group Policy. As you are probably aware there are a number of Group Policy related hotfixes in Windows 7 / Windows Server 2008 R2 Service Pack 1 which is about to be released (on Feb 22nd 2011) however these two particular patches are listed as being required even for Service Pack 1.

I do note that KB981704 has been out for a while and seems to have been just updated to reflect that it is still required for Service Pack 1.

KB981704 – The file name of an ADM file is displayed incorrectly in the GPMC report in Windows Vista, in Windows Server 2008, in Windows 7 or in Windows Server 2008 R2.

KB2460922 – Group Policy preference item-level targeting does not work for 64-bit versions of Windows 7
