Oh Windows 10, you don't do yourself any favors.
Ironically, just as I was reading this article, my screen flickered black for a moment then came back, and I now have no audio. Windows 10 (1803, not even 1809) has just "helpfully" auto-installed new - faulty - drivers for my graphics & HDMI display audio. I've now spent 10 minutes trying to roll it back, without success. Pardon me for venting my frustration in this comment.
Thanks, Microsoft. $##%@&!
