    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?

    Installing Windows 10 using Windows 7 key

    Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

    As for getting rid of Windows, delete the Windows folder.

    Windows 10 product key already in use

    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.
