WIN10 auto-updated my PC last evening. I saw the update went I went to power down and chose restart. Six hours later, when I went to bed, it was it was about half done the installation so I disconnected the internut cable. This AM, the little spinning icon was spinning. Hard reboot and same thing. Powered off. Connected the cable and booted. It auto-recovered. It's working. AGGGGHHHHBHH!
