My wife?s computer started to update Windows 10 last evening and after about 3 hours into the upgrade process it totally froze. I shut the computer down with the off/on switch and restarted it. It booted using an earlier version of W10. I tried to update and here is what happens. It processes the first 3 stages of the update process (download, prepare for installation, and configuring update) without a problem. When it gets to the last step, working to update, it gets to 87% and totally freezes. The full screen is Microsoft blue and the animated circle of dots that indicate that the computer is working is frozen. There is no cursor or other input modality. The only way to overcome the freeze is to shut it down and restart the computer as mentioned above. In looking over the update history the last successful update was on 1-10-2017. This must be a very recent update problem because I have not found any solutions Googling. Any suggestions?
