Microsoft's response to all this chaos...

A new Patch Tuesday, a new list of bugs – It’s kind of becoming a tradition. Several users have reported that this week’s cumulative update is breaking their systems. While that may be a slight exaggeration, but nobody should be expected to look for workarounds or fixes after installing “security” updates. In the latest of these issues, Windows 10 1803 users are reporting several different issues related to Edge, Task Manager, Windows Hello, etc.
