    Already recorded two reinstalls on the same machin, one install on a new machine, all activated using the same retail key. At the moment recording the upgrade process to 10, then finally the new install of the original 8.1 which will no longer accept my product key.

    Using one of my available 8.1 keys for this but what the hell, science is important

    It might take all night before I have the video here. It's half past 8 PM here now but luckily I am an insomniac.
    One must understand that individual failures do not constitute a company policy nor universal failure.

    Many people have reported a successful upgrade to Windows 10, fully activated, then a failure of an activation on a subsequent clean install - only to go back and do an upgrade again and have everything succeed as it is supposed to.

    Kari, these thumbs up are for the sacrifices you make in the name of Computer Science and just plain Geekery (Ha I coined a new word)

    The thing is, even if you could retrieve the product key of the underlying OS, it would be useless. If a valid 7 or 8.1 was upgraded to 10 and the 10 automatically activated, the underlying 7 or 8.1 key is flagged as used and can't be used to activate 7 or 8.1 on another machine.

    The key of an underlying qualifying OS is gone and invalid as soon as the upgrade to 10 has been activated.
    100% complete and utter nonsense.
    NavyLCDR, I agree with you.

    The activation page shows the following message (see screenshot below):

    This product key is being used on another PC. Please try a different key.

    Note: Click on the Call support option (see screenshot below).

    Note: The activation robot asks you how many PC's you have installed Windows on. The correct answer is number 1.

    I used to beta test Windows 7 and was always doing a clean install just about every month, and subsequently played around with Windows 8/8.1 and now Windows 10. I've got a couple of Windows 7 keys now in that "won't activate on the internet" window that I have to call Microsoft and tell the computer voice it's only installed on one computer in order to activate. And they are still good, after using them to upgrade to Windows 10 with.

    Maybe Kari is in the same situation, I don't know. Each Product Key does have a limited number of times it will activate automatically over the internet within a certain amount of time but until Microsoft sees a heavy repetitive use of the same key, it can be activated by phone.

    OK guys, this will take time, encoding in process but after that I need to do some basic editing and add explaining titles before I can post the video:

    The process as I did it:

    • Install Windows 8.1 Pro on a new machine, activate with a valid product key which had never been used before. A totally virgin key. Activation OK
    • Reinstall 8.1 Pro on same machine wiping the HDD, use the same key to activate. Activation OK
    • Reinstall 8.1 Pro on a new machine, use the same key to activate. Activation OK
    • Upgrade the last install to Windows 10. Windows 10 activation OK
    • Reinstall 8.1 Pro on a new machine trying to use the same retail product key, resulting this:

    Kari sounds like a warning tutorial in the making to me.

    Now run slui 4 from a command prompt and attempt phone activation. You probably hit the online activation limit using the same key so many times in a short period of time.

    Now that is interesting. The activation must use the original key then it seems.

    No tutorial is needed, Microsoft has made this so clear there's no doubt: when an upgrade to 10 is made from a qualifying OS, the underlying valid product key is used to activate 10. It will be flagged as used, a free upgrade to 10 does naturally not give you two activated operating systems, the underlying and the new one. Only one OS will be valid, the upgraded 10, its activation based on the valid underlying product key.

    Of course I could have done the last install with a generic Windows 8 key and then try to activate it from the settings, but the result is the same: key is used.

    I repeat the fact that the Windows 8.1 Pro key I used for this experiment was virgin, never used before. Those knowing MSDN, I only claimed the key today just before starting this experiment.
