    windows 10 key

    Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

    Lost windows 10 pro product key

    Why was I not asked for a product key when upgrading to Win 10?

    According to your spec you have Win 10 Pro, but perhaps that doesn't reflect your PC.

    You haven't stated which edition of Win 10 you have on this machine, nor what your Win 10 key is for.

    For example, if you already have Win 10 Pro and your key is Win 10 Home, that would be a retrograde step.
