Microsoft just forced a Win10 upgrade on me and I had the same problem with the missing network protocols. I spent six hours working with three techs at the Answer Desk and nothing they tried worked. I gave up on them and tried deleting my anti-virus application (Avast). Restarted my PC, and that fixed the problem. I then reinstalled Avast, and everything is now working. Hope this helps someone else.
This post by MRoth did it for me! I deleted AVAST and rebooted. The internet connection now works. :)
This is on a Comcast/xfinity connection. I called them and they were of no help. Told me to call MS. I did but they were of no help in getting me connected, although I now have a case number. When they call back I will let them know that the problem was AVAST.
