Customer running ZCM2017 update 2 and WIndows 10 build 1709.
Now they have some machines that have got the 1803 update via WIndows Update.
After that the ZenIcon in the systemtray does not appear and user seems not to be logged in in Zenworks.
When manually starting ZAPP, trayicon appears, but grey, not signed in.
Chosing sign in makes the user signed in, and all works fine.
Seems like something in the 1803-upgrade stops agent to start.

Have now stopped 1803 in WSUS, but people can have the isea t manually update.
I have not tried newinstall of agent on newinstalled 1803.

Can start SR if needed, but wanted here first to check if this is known?
Any ideas?
