Since Wednesday. I think I possibly didn't give the upgrade enough time to activate before formatting.
You didn't let the upgrade get activated?
If so, you may have to do the upgrade again!

You're given the choice to perform a quick or more secure format (in case the computer is not being kept) just like when you install from DVD.
The reset option is a complete reinstall (link).

Yes,
If the upgrade didn't activate - then you will need to go through it again
I didn't even think to check stupidly! However tonight I have followed the guide in the OP. So in my case, with a clean install which did not want to activate, I did a clean install of 8.1 and confirmed it was activated. I upgraded to W10 via USB media and again confirmed it was activated. Took a copy of the key which I put in when doing a clean install of W10 and it activated straight away. Happy days!
Good news
Happy to help Kyo, thank you
