Thank you for the screenshot, I think you need to take your system back to the computer shop, the command indicates an OEM_DM key, which should be installed on the motherboard, but ShowKeyPlus indicates no OEM key is found on your system and the product key indicated is a generic key, no OEM or Retail key is found.

    1

    Your Screenshot indicates an OEM_DM licence, that type of licence is usually pre-installed by the PC manufacturer and the licence should be on the motherboard.

    What happened on your PC before Windows was not activated?

    2

    Please provide a screenshot of the activation error indicated in the Settings App.

    3

    Download the free ShowKeyPlus app from the Microsoft Store.

    Please provide a screenshot of that app window and please hide your product key in the screenshot.
