WMI filter
The filter for Windows 2000 is used to prevent computers that are running later versions of Windows from applying the GPO. You cannot use a WMI filter to apply a GPO to computers that are running Windows 2000 because that version of the operating system does not support WMI filters.
You can also create combination filters when required by your design. The following table shows query statements for common operating system combinations.
