    I have Windows 10 Pro keys' but cam't remember which is already used.


    Like the title says I have two Win10 Pro keys and used one to build my PC last December. Now I need to use the other but can not remember which is already activated. I have used a couple apps to try to find out what my current serial # is. None of the results match my purchased keys though. Is there a way to find out which one is already on my PC?

    :)

    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?

    windows 10 key

    I am trying to do this on my main rig which has Win 10 pro.

    The link no longer shows an option for Windows 10 Pro. I think they bundled it and it will react to keys instead. Hate to try though.

    Most importantly, it's letting me download 1511 build which I already have.

    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.
