As rare as Windows (10) re-installations are these days, a fresh installation being immediately broken has happened at least twice now.

Some applications can't save their settings and Google Chrome now won't open most Google services due to NET::ERR_CERT_AUTHORITY_INVALID and HSTS errors.

I'm supposed to be doing some major FileSieve work over the next few days!

Edit: More information on the Chrome issue.

But first, system information: Windows 10 x64 (Creator's Update), GeForce GTX 770, Skylake i7 6700K CPU, 32GB RAM; all updated drivers

The cert problem in Chrome is something I've seen a bit too often over the years; with no change in the OS environment, Chrome will start giving the NET::ERR_CERT_AUTHORITY_INVALID error, along with a message that the site can't be seen at all due to it using HSTS. But this is new in that its specifically the Google services, and Gmail's missing icons.

Microsoft Edge works without issues. For the first time - ever.

This is happening for YouTube, the Chrome Store; not sure if it's affecting non-Google sites as I haven't browsed many today. One difference, though, is Gmail works but its web-fonts(?) are blank. Uh, how do I show a screenshot in Markdown...

The vertical lines denote where I snipped the image to reduce its width.

The screenshot shows that various within-button icons are entirely missing, including the images displayed within each tab.

Additionally, the Hangouts Chrome extension won't sign-in.

Edit 2: Argh, re-installed Windows and everything works fine - except Chrome. It's now complaining with the same error above (seems it's when I restart Windows?), but thankfully I'm able to fix it via the following:

Fully exit Chrome via the systray icon
Open a command prompt in Windows
Type `ipconfig /flushdns`, and hit Enter
Open Chrome and it works correctly
