only, it ended with an error ! error code 0x8024200D
Searching around, it turned out that errors are more common than
one would have expected from the os-turned-into-a-service ...
Searching for a solution I reached the "reset windows updates" solution and it worked !
what you need to do is
- download the script they suggest in the solution (as you can no longer download it,but could copy it when this self-doc was written, I include it here on my github, as a precaution and you can download it for your own use)
- run it from cmd (as administrator).
- restart your computer.
- now go to windows updates, and let it try to install the fall creators upgrade....
Take into account that a the successful upgrade required several hours of downloading.
And looking back at the surprising amount of hours that a simple upgrade has taken, which resembled more of an operating system major version upgrade, this raised doubts why do I bother with windows any more...
