|Export a WMI filter|
In the Group Policy Management Console (GPMC) console tree, right-click the WMI filter that you want to export, and then click Export.
In the Export WMI filter dialog box, select a secure file system location from the Save in drop-down list box, type a name for the filter that you want to export, and then click Save.
To secure exported WMI filters, ensure that only authorized administrators have permission to access the folder to which you are exporting the filter.
WMI Filters are only available if at least one domain controller in the domain is running Microsoft Windows Server 2003. The same is true for WMI Filtering on the Scope tab for Group Policy objects.
You can also export a WMI filter by clicking WMI Filters and, in the results pane, clicking the Contents tab, right-clicking the filter name, and then clicking Export.
GPMC can import only .mof files that contain a single WMI filter.
