GPO Preferences – Target Windows 7 32/64-bit and hotfixes for filtering

There is known issue with GPO Preferences targeting on Windows 7 64-bit.
You need to install a fix described here:

Group Policy preference item-level targeting does not work for 64-bit versions of Windows 7
http://support.microsoft.com/kb/2460922

To target Windows 7 32 and 64-bit correctly in GPP you need to use Environment Variable %Processor_Architecture% in Targeting Editor.

%Processor_Architecture% = x86 for Windows x86/32-bit
%Processor_Architecture% = AMD64 for Windows x64/64-bit

There are also two hotfixes related to GPP filtering –  for security group filter and LDAP filter:

976399     FIX: You cannot apply Group Policy settings on a computer that is running Windows 7 or Windows Server 2008 R2 when security group filters are used in Group Policy preference settings
http://support.microsoft.com/kb/976399

976398     LDAP filters in the Group Policy preference settings do not take effect on a computer that is running Windows Server 2008 R2 or Windows 7
