Cannot start Hyper-V Virtual Machine after install of KB4343887


I wanted to report that I was unable to start any Virtual Machines in Hyper-V after an automated overnight update was installed last night: KB4343887 Cumulative Update for Windows Server 2016 for x_64-based systems.

After the update was installed, when trying to start any VM, it failed with an error message very similar to the following:

"Failed to start the virtual machine ‘test’ because one of the Hyper-V components is not running."

After removing the update, I was able to start the VMs.
