For this reason, client-side targeting GPOs are typically linked to organizational units (OUs) containing the computers that are to be assigned to the respective WSUS groups rather than to domains or sites.
The policy setting will be applied upon the next refresh of Group Policy, which happens every 90 minutes by default.
