The servers being updated by the WSUS were not being affected because we were not pushing KB890830 (Windows Malicious Software Removal Tool). The majority of our servers are updated viaĪ WSUS but our DCs were excluded from the WSUS policy because we wanted to control when updates were applied and when the DCs were restarted.
