CAUSE

During the installation of update 952265, the Windows Update service tries to stop any running processes that are associated with the Forefront Client Security client. This requires the SeDebugPrivilege user right. By default, a Server Core installation of Windows Server 2008 does not grant this right to the Windows Update service.
