    Win10 updated from Win8 - does clean install loose product key?

    Use this option. With Internet connection, if asked for product key, click on "Skip This Step" or "I don't have a product Key". Windows will be activated automatically.

  3. Need product key for Win10 re-load

    • Hi, I had to do a factory reset on my Toshiba laptop (multiple problems, black screening, etc.). I downloaded Win10 from MS site and have loaded it back on but product key required. I have no product key because the previous install was free upgrade from
      Win7 a few years ago.

    Where to find Win10 product key?

    Cannot upgrade to Windows 10 - Unique Product Key situation

    No... let me try again.

    • Old computer is running Win7 Pro (SP1) with a Product key I have from a few years ago. The Product is activated already, but I do NOT use this computer at this point, so I didn't worry about using the Product key when moving to the new computer (see below).
    • New computer is running Win10 Pro, with data and OS migrated from the Old computer, (same Product key as above), then Upgraded to Win10 (without getting a new Product Key).
    What I am trying to do now...

    • I want to upgrade the OLD computer (Win7 Pro) to Windows 10... using a new Product Key I just purchased.
    • I have tried to do this internally, and also using the ISO burned to a thumb drive. But it does not want to work.
    • Steps:
      • Start from USB drive.
      • Enter New Product Key (or click "I don't have one").
      • Install initiates and then tells me to restart from Windows and then open the installer again to continue.
        • At this point, I actually need to Quit the installation to restart the machine.
      • When restarted, I go to the USB drive and restart/resume the installation process.
      • I have tried to download and not to download updates, but when the installation fails, I see the message, "Something happened" and "Setup has failed to validate the product key".
      • NOTE This happens if I enter the NEW Windows 10 Product Key, or if I skip that step (which I assume means that it will use the old Windows 7 Key for the upgrade).
