Networking not working after Windows 10 Update (version 1511, build 10586.3)

My device:  Lenovo ThinkPad Yogo 2

After applying the latest Windows 10, update, version 1511, build 10586.3, all of my networking was jacked up. I was unable to connect to any wireless networks (showed a small amount of sent packets, 0 received, and great single strength). I attempted to uninstall the device from device manager and when I rebooted the device reinstalled, but still nothing worked.

When I got home I attempted to use my USB Ethernet adapter and even that didn’t work.

The Solution

NOTE: Following the procedure below will reset all networking. This includes Hyper-V and VPN interfaces. (My Cisco VPN client rebuilt everything automatically when I attempted to connect).

Run “netcfg -d” from an admin command prompt, then reboot and reconfigure networking.
