    I will run the tools from this forum and see what I get. I did use some tools, not from here, to see what keys were in the BIOS and registry and they were not the same. This was after upgrading to Win 8.1 Pro from Win 8 OEM.

    Original key was XXXXX-XXXXX-XXXXX-XXXXX-2R243 from BIOS
    Registry key was XXXXX-XXXXX-XXXXX-XXXXX-7QvP2
    showkey should give you all the info you need, and read all the keys you need, https://www.tenforums.com/software-ap...7-showkey.html My laptop has an OEM 8.0 Core key but was running 8.1 Pro with my MSDN key. I got 10 Pro with the free upgrade.

    I can get up to 5 each of 10 Home and 10 Pro. Thing is though, if your MSDN subscription runs out and you don't renew, you can't request any new keys. You get to keep what you have but you can't get any new ones. That's what happened to my TechNet subscription. It's frozen now. No Windows 10 keys can be had.

    Entering the two keys into ShowKeyPlus returned invalid for both but upon looking at the ShowKeyPlus results the Original key I posted earlier is the one showing up as the Original Key and OEM key.

    Showkeyplus on the Win10 laptop shows:

    Looks like you are going to have to revert back to Windows 8.1 Pro and do another upgrade. I would use Media Creation Tool to download a Windows 10 Pro ISO so you know that is exactly what you are trying to upgrade to. Run setup.exe inside the ISO from Windows 8.1. If it asks for a product key during the upgrade, something is wrong.

    I have upgraded a laptop that had a Windows 8.1 Core (Home) key in bios that was upgraded to Windows 8.1 Pro with a product key for 8.1 Pro, and it upgraded to Windows 10 Pro. So it is possible. Not sure why your Windows 10 upgrade did not recognize the 8.1 Pro that it was coming from, but looks like it didn't.

    That shows 8.1 Core to 10 Home, as far as I can tell anyway. I don't see Pro in there anywhere? In case your not aware, the MSDN ISO's will read the OEM embedded key automatically and install the matching version automatically, without asking. Your not asked to enter a key either. For Windows 8/8.1 anyway. My laptop has an 8.0 Core OEM embedded key. If I install with my 8.0 MSDN ISO I get 8.0 Core, use my 8.1 MSDN ISO and I get 8.1 Core. To get it to install Pro right from the get go I have to add a PID.txt file with my Pro key to the sources folder. Or use add features to get to Pro after the install.

    alphanumeric - Thanks for the info, seems I'm getting schooled on the changes to the installation process for WIN 8/8.1 plus Win 10. So what you described is how I had upgraded from Win 8 Home to Win 8.1 Pro using an ISO image from my MSDN subscription. My bad, so I either go back to Win 8.1 Core and use the ADD features to get Pro then do the free Win 10 upgrade all over again or just leave it the way it is with the understanding the Win 8.1 Pro key is still available.

    Yeah, it's a bit different with the embedded keys and the auto detection part. I was learning as I went also. I wasn't an MVP when I got my laptop so I started with 8.0 Core. Then went to 8.0 Pro with my MSDN key latter on. Then to 8.1 Pro. All the fun started on the clean installs. The other wrinkle is because the upgrade to 8.1 from 8.0 was free, Microsoft coded 8.1 ISO's to use 8.0 keys and 8.1 keys, even OEM embedded keys. My guess is you thought you installed Pro but it was actually Core that got auto installed. That's what it looks like from that showkey screen shot. I never get asked to enter a key when I use my windows 8 MSDN ISO's on my laptop. The other way to do it is to download just Pro from here, http://windows.microsoft.com/en-us/w...-refresh-media It will ignore a Core OEM key and prompt for a Pro key. Then you can just install Pro right from the get go.

    Your options are pretty well as you describe. Keep the extra Pro key for another PC, or start over and install 8.1 pro to get 10 Pro.
