    It's called DefaultProductKey for a reason, it's default generic key

    [Just speculation]

    I think they've dropped MSDM table as there is a loophole: one can get the MSDM key & use it as a retail key to activate another device by phone activation. As far as I remember, Please-8 himself discovered & posted it in MDL.

    Now for the OEM: DM activated devices, HWID + unique OEM: DM key are saved in MS activation servers.

    :rolleyes:

    OK - possible.

    But how do that the OEMs practically. Do they inject every hdd image with an individual OEM key ?
    (In Windows 8 the OEMs inject every BIOS with an individual OEM key)

    If we find another win10 system, it would be easier to tell. I can only assume they OEM setup is done at the OEM. Win8/8.1 OEM would contact MS for each system (automated), authenticate -> request -> get -> tattoo each system. Now they may have gone back to Win7ish type and have a single image as master image and just build their doodoo machines.

    Looks like combo, OEM do their thing and still do the auth->req->get->tattoo for the system.

    What does the following mean:

    • I have a DVD with Windows 10 x64 Home and Pro (downloaded from Microsoft).
    • When I use this DVD for an installation in a virtual machine the setup ask me for a key (to make a decision between "Home" and "Pro")
    • When I choose "skip key entry" then the setup offers a menu with both versions.
    • When I go back and enter a key (e.g.: Win 10 RTM Core OEM:DM) then the menu with the both versions doesn't appear (because I have made my decision by entering a "Core / Home" key)
    • When I boot from the same DVD on the new notebook I don’t see any key question or menu. Setup installs automatically the Home version.
    Same procedure like Windows 8.

    So I think a unique OEM key is still there in the BIOS - but not in the MSDM table.

    If you have OEM key just download windows 8.1 iso with rufus then make UEFI usb boot (link......../windows-8/create-reset-refresh-media -cant post links). Do a clean install 8.1 then reserve windows 10 and do just upgrade. You dont need to enter any key it will read from bios.
