Importance of testing Windows updates before installing to Production servers

Importance of testing Windows updates before installing to Production servers

This morning I got important reminder that also Windows updates needs to be tested before installing to production server. It seems that latest Windows update might break Windows Server 2016 running on Vmware virtualisation.

In my case, the environment was still on staging stage and there was no active users. Servers didn't boot and I got an error: Inaccessible Boot Disk. I got uninstalled the updates that have been installed today. Here is link how to do it:
