Steps to reproduce the problem:
1. My WebGL would not work in Chromium, latest release, so I called my manufacturer's tech support. They walked me through a bunch of obvious possibilities (which I'd been working on for the last 24hrs), and finally advised me to either RMA the device, or restore the factory image. I chose the later.
2. After reinstalling the factory image, I reinstalled Chrome and tried again. Everything worked.
3. Windows update ran at some point, and when I came back this morning, WebGL was again not operable.
4. I rolled back as many windows updates as I could and tried again. Nothing. 
5. I ensured that:
chrome://settings/ Use hardware acceleration is ENABLED.
chrome://flags/ Override software rendering list is ENABLED.
chrome://flags/ WebGL Draft Extensions is ENABLED
chrome://flags/ WebGL 2.0 is ENABLED

What is the expected behavior?
WebGL works on any page upon which it it is implemented.

What went wrong?
All pages report that my browser does not support WebGL. Chrome reports that my processors do not support WebGL.

Both statements are incorrect.

Does it occur on multiple sites: Yes

Is it a problem with a plugin? No 

Did this work before? N/A

Chrome version: 56.0.2924.87  Channel: stable
