    Hello guys, is there any PID Key Checker that can check who issued Windows 10 Product keys?
    For example:

    Issued by: MSDN
    Issued by: Azure (Dreamspark/Imagine)
    Issued by: Microsoft (Commercial use)

    So you can check if the key is genuine retail key (like the ones sold on Microsoft) or if it's a MSDN/Azure retail key.

    Thanks!

    I've got a Office 2010 key, which cannot be decoded by the latest version of the PID checker. How can I help you to identify it?

    Hello . First of all thank you for this tool as I can verify product keys before installing.

    One question I have is does the tool actually imply that the product key has not yet been activated even if it says that the product key is valid?
    This concerns me as I have old retail copies of Windows 7 lying around in my stockroom and I have no idea if these copies were already used/activated on other PCs before it was handed over to me.

    Any help will be greatly appreciated.

    Thank you.

    No, a "valid" product key in the sense of an offline check only means that it passes the offline sanity checks and is syntactically correct (if you just made up a key it would certainly not pass). Such a key will at least allow to install the OS SKU it is intended for.

    Validity checks for online activation are done by Microsoft's activation servers. And no, it is unfortunately not possible to check if keys are Genuine (allowed for activation). MS does allow such a check only for Volume Multiple Activation Keys (MAKs).

    tl;dr: If a Retail key will successfully activate can only be found out when actually using it.


    Edit: There seems to be a reset of long-unused Retail keys after some time, on MS activation servers (machine activated with that key has not contacted the MSAct server for a long time). The keys will work again after that, but, you won't know unless you try.
