    Hello,

    I have a laptop that was bought with a licence of Windows 8.1 Pro. It has a COA label with licence key hardcoded in BIOS.
    These came with an HP DVD of Windows 8.1 Pro OEM filled with HP software and other crap.

    I downloaded some msdn windows 8.1 pro images.

    Is it OK to use an OEM key on non-OEM images? Like OEM key on VL images, or OEM on standard images?
    Will I have any legal issues with it (like microsoft audit team, or others) ?

    My oem key activates on both standard images as well as vl images (but activates as OEM of course).


    Thank you

    You simply can use this great MDL project, it wil use the oem:Dm bioskey and activates it legit.

    Yes but it doesn't really answer my question.
    Windows is already activated using the OEM key. Everything is OK. I'm only wondering if there are any legal issues of using a different ISO than the one supplied by manufacturer.

    Afaik normal 8.1 iso's can't readout the oem:Dm bioskey so that's why i advised to use the MRP files to modify the Win 8.1 Multiple Editions ISO (MSDN Retail) to be able to automatically readout and use the key combined with the correct certificates.

    I believe that manually entering the oem:Dm bioskey without installing the appropriate certificates won't activate windows.

    All MSDN iso's can be downloaded at the top link in my signature.

    As far as other iso's will work, if the setup accepts the key, it's legal, but keep in mind, only entering the oem:Dm key won't work/activate.

    Wrong - starting from Windows 8, the setup.exe can read OEM: DM key stored in MSDM table & determine appropriate SKU to be installed.

    Unlike OA2.x OEM:SLP, there is no concept of certificate in OA3.x OEM: DM activation.

    Give this a read to clear out the concepts.

    @Ocygord

    There shouldn't be any problem. The VLSC ISOs come with an extra SPP package but I don't think any audit team will notice that.

    :)

    And now please answer the OP's question instead of stalking me?

    If you were to preserve the OEM key, does it only work with other "Pro" editions?

    And is that method posted above technically legal?

    As far as I know this procedure is legal for the Standard Edition. You can even download a Windows 8.1 Pro Version at the following Microsoft Page without entering a License-Key:

    https microsoft.com/en-us/software-download/windows8ISO

    ... and activating a Computer with an embedded OEM:SLP Key without entering a Key during the Setup.

    I don't think this will also work with a VL Edition ISO or any other Edition, because the Version specific License-Key is "hardcoded" inside the MSDM Table.
