Being older than some rocks, I get up often at night. When I got up at 1:00, I turned on the computer. Nothing. I checked Windows Update and was shocked when it asked if I were ready. That would have been 1:15 and by 1:45 I had Windows 10. The downloading and installation was automatic. My only real input was to tell it I preferred English. I really have to congratulate Microsoft on a fantastic rollout for Windows 10. I'm almost nostalgic for the agony and ecstasy of the older OS installations. But, not quite.
