    Can I reinstall Windows 10 on my computer after upgrading with free upgrade?

    Once you’ve upgraded to Windows 10 using the free upgrade offer or Media Creation Tool on an activated Windows 7 or 8.1 PC, you will be able to reinstall, including a clean install, on the same device. You won’t need a product key for re-activations on the same hardware. If you make a meaningful change to your hardware, you may need to contact customer support to help with activation. You’ll also be able to create your own installation media like a USB drive or DVD, and use that to upgrade your device or reinstall after you’ve upgraded.
    Just in theory ^^
    I did it and it doesn't work, windows is not activated after the clean install...

    Yes I can confirm that. If you do clean install, windows 10 will not accept your previous legal win 7, 8 or 8.1 product key.

    If you only did a clean install to Windows 10 from Windows 7/8, then the free offer Windows 10 will not be activated unless you had already did what I posted above first on that PC.

    If you change to a different edition, such as the Educational edition, even if you upgraded first it will still require a new key. The upgrade activation is only valid with the same edition you have installed, or upgraded.

    So, for example. If you upgraded your Windows 7 Home Premium to Windows 10, you would have Windows 10 Home. If you wipe the drive and re-install Windows 10 home (same edition... be careful not to confuse single language with multiple language) then it will continue to be activated.

    If, however you upgraded your Windows 7 Home Premium to Windows 10 Home, then wiped and installed Windows 10 Educational, it will NOT activate and you will need a new key because Educational is a different SKU.

    In that case and if you did what Mystere posted above, give it a day or two of trying to activate.

    The MS activation servers have been under heavy load, and not always able to activate.

    I have the same problem.

    I upgraded my 8.1 pro which worked fine.
    The fresh install there after refuses to activate, MS support (line 1) were unable to help, it has been escalated to line two who are due to call me tomorrow.

    I'll let you know how it goes.
