Yesterday, I got the usual Windows message about needing to restart my Dell OptiPlex 3010 computer (running Windows 10 Pro); I accepted it, closed down all apps, and let it restart. Â After a while I noticed that it was hung on a black screen with only a circle of white dots revolving on the bottom of the screen. Â I left it overnight, but it was the same the next morning. Â I turned it off, left it for a minute or so, and turned it back on; it started to reboot, but when the blue window appeared in the middle of the screen, the circle of white dots appeared, with a brief message "Attempting to complete installation" (or some such). Â The white dots kept on circling for a few hours, and again I turned the computer off, waited a minute, then turned it back on, this time holding down the F8 key in hopes of getting into Safe Mode. Â That didn't happen, but this time when the circle of white dots appeared, under it was a persistent message "Recovering your previous Windows version". Â This time the reboot was successful, ending up with Windows the same as before, as far as I could tell.
So what was going on? Â Was there a massive SP-type upgrade that amounted to a new Windows version? Â Will the same thing happen on my other two computers, also running Windows 10?
Is it an endemic Windows 10 issue? Â No. Updates are fine on my machines.
