I do not need a solution (just sharing information)
Hello Everyone,
As most of you already know, SEP 12.1 and 14 clients which have had Windows Update KB4056892 installed have been experiencing an issue, where an alert on the SEP system tray icon warns of "multiple errors". This issue is described in the following article:
Endpoint Protection system tray icon reports there are multiple errors after updating ERASER to 117.3.0 and Microsoft Update KB4056892

SEP 12.1 RU6 MP5 or earlier clients can also encounter the following issue:
ccSvcHst.exe crash after applying the January 3rd, 2018 Windows Security Update to a system running SEP 12.1.x

Please note that SEP 12.1 RU6 MP6 or later will still experience the system tray icon error behavior, but will not encounter a ccSvcHst.exe crash as a result of applying the Windows KB.
At this time we do not require additional data for either of the above issues.

Our Developers have provided the following update to offer some clarity around these issues:
These issues are unrelated to the ERASER 117.3.0 Engine update. These issues impact all Operating Systems that received the Windows Security Updates released on January 3rd, 2018.
Ongoing investigation indicates that the tray icon error issue described in TECH248552 has no functional impact on the SEP client with regards to our protection technology stack, but out of an abundance of caution, we are recommending that SEP 12.1/14.0 customers please hold off on applying the Windows Security Updates released on January 3rd, 2018 until our investigation has concluded.
