Known Issues - June 2018 Windows 10 version 1607 1. Addresses an issue that causes BitLocker to go into recovery mode when updates are applied. 2. Addresses an issue that might sometimes lead to incorrect checks for applicability during installation of Windows Updates. Windows 10 version 1607 and Windows Server 2016 need KB4132216 (https://support.microsoft.com/en-us/help/4132216/servicing-stack-update-for-windows-10-1607-may-17-2018) prior to installing the June 2018 update. Recommendation is we can proceed with pilot patching. For Windows 2016 servers, make sure to install KB4132216 before patching June 2018 updates. For Windows 10 version 1607 clients, we need to deploy KB4132216 first. KB4132216 does not require a reboot after install. So we can push it out to the client without user notice.
