    Fresh Install of Win 10 without Serial Key?

    Looking to reformat a laptops HDD, and then reinstall Win 10 fresh. The problem is it came pre-installed with Win 8 and I did the free upgrade to Win 10. How exactly would I re-format the HDD, reinstall Win 10 and ensure it reactivates properly? I don't see a Win 8 serial key anywhere in the contents of the box.

    How to find product key for pre installed Win 8, updated to Win 8.1 to update to Win 10?

    Win 10 Pro upgrade using Win 8 Pro product key

    I just bought a new computer running Win 10 Home. When I went to upgrade to Win 10 Pro using my Win 8 Pro product key from my old computer, the upgrade wouldn't activate.

    Now I'm stuck with a bunch of error messages (mainly 0xC004C003) and am being told windows isn't activated. I can't seem to get my activated Win 10 Home back.

    I don't have a product key for the Win 10 Home because it came pre-installed. There's no product code recorded on the packaging or labelling on the device.

    So:

    How do I either

    • activate the Win Pro upgrade, or
    • Get my activated Win 10 home back?
