What just happened?

Hi

I got so fed up with Windows 10 constantly updating as well as any number of annoying other things, that I decided to go back an do a Clean Install of Windows 7.

But within Minutes of doing that, I was getting pestered by the 'Nag Screen' urging me to update to Windows 10, where eventually it beat me into Submission and lived in hope that they had sorted it out.

And so I used my ISO disk to Upgrade to Windows 10

Everything was going well right up to the very last bit, when it asked me to enter my Product Number.

Obviously I didn't have one but this time there was no way to Skip filling it in and I couldn't continue without out.

Has this happened to anyone else?

Previously, they have allowed you to 'Skip' filling it in but not this time.

At the page where you were asked for a product key, did you see a " I do not have a product key " option ?
If yes, you could click that option and continue.

Have you not got a COA key anywhere on the computer? Your Windows 7/8 Key should work for upgrading even if you don't have one for WIndows 10.

You have the wrong edition/version of Windows 10 ISO downloaded. Need to go back and download the edition/version of Windows 10 that matches your installed Windows 7.

Yes I had a product Key for Windows XP and for the Windows 7 Upgrade disk and it automatically activated Windows 7 for me, which is why I couldn't understand why it asked for my product key at the end of the process, with no option to 'Skip'

That ISO disk has always worked before, I didn't do anything different.

The OP doesn't have to enter the Win 7 key.
He had Win 10 installed once, then he went back to Win 7.
Once his Win 10 was installed and activated, he is digitally entitled.
He does not need a key to reinstall Win 10 anymore.

Yes, I get that but I couldn't get into the programmme without entering it, maybe I should have tried entering the Win 7 number but I've not had to do that before.

In Windows 7, open an elevated ("run as administrator") command prompt. Run:
slmgr /dlv
and post the result window here, please. It won't have any unique identity info in it, so you don't have to blank anything out. That will help us troubleshoot what the problem might be. This is mine (from Windows 10, though):
