16.2.5 cleared it up for me as well. Have 2 VMs on my desktop and my main one that I keep up to date failed to boot with the Unsupported Processor error. Started up my backup and it worked until I ran windows updates. Luckily found this thread and saw 16.2.5 mentioned at the bottom by @foobar4711 and @joshiga and I'm back up and running. Thank you!
