    Where are the Activation Product Key Rights ?I Do Not want to Revert / Rollback, because the Original Factory Installed Windows was 10.it´s a New Machine,i cannot revert / rollback to W8.1Repeatedly, Microsoft CEO, Satya Nadella said: "We want to go from users needing Windows to choosing Windows to loving Windows."https://www.windowscentral.com/how-downgrade-windows-10-windows-81The problem is the Key, does Not allow to Clean install Windows8.1i have done clean installs, i know how to do it, thats Not the problem.The problem is the Key stored in the UEFI of the machine.i have tested Windows 8.

    Windows 10 OEM key won't work on Windows 10


    Okay. The OEM edition is Win 10 RTM CoreSingleLanguage OEM: DM according to ShowKeyPlus. Should I install the Win 10 home single language?

    No, it is not a system builder. Its DM version
