Microsoft has just fixed the issues Morphisec and Cisco users have experienced with the October 2018 update of Windows 10. Those who use Morphisec’s security software and Cisco AMP can now try installing the October update again. But the company has a few conditions before users should attempt to upgrade again.
Morphisec Protector users need to have at least version 2.4.8 to update. While Cisco AMP for Endpoints users need at least version 6.2.3.10814 before reinstalling the update. The upgrade block still exists for versions earlier than these versions. If you want to see the other remaining known issues with the update, you can check it out over at this link.
