GPO with Filter WMI for OSArchitecture

Hi,

I use WMI Filter GPO with Windows Server 2012, when I filter by the version of Windows it works, by cons when I filter by OSArchitecture it does not work.

my goal is to deploy the parameters based on the system architecture 32- or 64-bit.

the filter I use is:

Windows 7 64bit:

SELECT * from Win32_OperatingSystem WHERE Version LIKE "6.1%" and ProductType = "1" AND OSArchitecture = "64-bit"

and Windows 7 32bit

SELECT * from Win32_OperatingSystem WHERE Version LIKE "6.1%" and ProductType = "1" AND NOT OSArchitecture = "64-bit"

please, do you have an idea about the problem?
