I ran this twice. The first time overnight. In the morning, the PC loaded up the previous version of Win 10,
So I reran it and watched the procedure. Did the Option 2 then Option 18
"The system reboot in 60 seconds. Please save ..."
PC restarted automatically.
PC "Configuring for Windows 10 0%
.... 100% complete" (ran all the way to 100% over about an hour).
PC "Restarting"
PC "Working on updates 0% .. 1%. Don't turn off your PC. This will take a while. Your PC will restart several times."
After 1%, the PC abruptly shut down, screen went black and did not restart.
Manually restarted PC.
PC "Undoing changes made to your computer"
Then prior version comes up. So no install of update.
