A Dell system will have the licence key embedded in the bios.

If you open a Command prompt (Admin) and enter

wmic path SoftwareLicensingService get OA3xOriginalProductKey [press return] it should display the 25 character product key.

    Hi, I'm John! I will help you with this.

    To help narrow down the issue:

    1. Can you share if you made any recent hardware changes, like replacing the motherboard or hard drive, before the activation issue started?
    2. Also, when you try to activate it, do you see any specific error message or code on the activation page? You can check this by going to Settings > Update & Security > Activation.
    3. Lastly, do you remember if your laptop originally came with Windows 10 Home or Pro?
