    Hey guys,
    I've recently upgraded to windows 10 and made a mistake. I activated the office 2016 preview with KMS. For whatever reason, my vaild windows 10 product key got overwritten too, acoording to the changed PID.
    What should I do? Do I need to go back to win 7 and Upgrade again?
    Thx for the help

    Oh, my dirty eyes!

    I think you can just do this in command prompt:

    slmgr -ipk key number here

    Or go into Update & Security > Activation in Settings app and enter the key.
