    Is it possible to see which windows 7 key was used to update to 10?


    I have three retail copies of windows 7. I had 3 computers for them. I now have two computers and a spare key.
    The problem is, I am not sure which key is the spare key.

    Is there any way to tell which windows 7 key was used to upgrade to windows 10?

    Try this utility, https://www.tenforums.com/software-ap...7-showkey.html If they were upgraded (not a clean install) this may retrieve it for you. Other than that, I don't know of a way.

    Good stuff. On an upgrade the key is still in the registry somewhere, if you know where to look. That utility does all the hard stuff for you.
