You can use WMI filtering to specify the devices in an organizational unit (OU) to which a Group Policy object (GPO) should be applied. A WMI filter is composed of one or more WMI queries. When you link a GPO to a new or existing WMI filter, the GPO's policy settings will be applied only to those devices in the organizational unit for which the WMI queries evaluate to True.

The following example shows you the correct format for WMI queries. Notice that <expression>is any WMI Query Language expression.

Copy Code 
“Select * from WindowsMobileDevices where <expression>”.

In the following example, the policy settings associated with a GPO that links to the query will apply to managed devices where the device language is U.S. English.

Copy Code 
Select * from WindowsMobileDevices where DeviceLanguage like
“en-us”
