    Hello all,

    We have developed product licensing model based partilly on windows product key. The key in question is the one shown in computer properties and not the one you enter yourself on activation. ( Why do they share the same name..?)

    When upgrading from 1703 to 1709 this key all of a sudden got changed, rendering the application license invalid. I've never seen this key being changed on previous windows upgrades, clients or servers.

    So why was this key changed and is this something we can expect on future upgrades aswell? If so we need to redesign our license model, replacing the product key with something else "machine-unique".

    Best regards

    Bjarne

    Hi Bjarne,

    Thank you for posting here.

    I am not sure whether it is a bug issue for windows 10 operating system, you can post the issue on windows 10 feedback.

    The next version will update and solve it.

    Based on my search, the author mentioned that the default key will not activate the system, just take you to Pro so you can activate using a valid Pro key that you will provide.

    You can see the document. I don't think that the problem is development issue, you could ask the issue on community website.

    Best Regards,

    Hart

    Hi,

    This is not an windows activation issue, frankly I don't understand your answer.

    Its about the id generated by windows, see pic below.


    We use this id as part of our license model in our software to keep a license unique and bound to a specific machine.

    This id has, until 1709, been static and has never changed. (unless you reactivate windows obviously)

    I just want to know if I can rely on this id on future windows updates of if we have to rewrite our license model, omitting/replacing the product id.

    Edit: I noticed I incorrectly referred the Product Id as Product Key, sorry for this.

    Hi,

    Thank you for your feedback.

    >>I just want to know if I can rely on this key on future windows updates of if we have to rewrite our license model, omitting/replacing the product key.

    Since your issue is not related to development issue on desktop. This problem is beyond ability of the forum.

    I am not sure whether you can reply on this key on future windows updates.

    You can write your feedback and post the address of your feedback, I will vote the reply, i believe that the Microsoft development person will see the issue.   

    Best Regards,

    Hart

    Until Microsoft publicly documents that a Product ID is unchanging then reliance on it is at your own risk.
