    To regain access to your Windows key after a BIOS update, you may need to follow these steps:

    1. Check the MSDM Table: Ensure that the MSDM (Microsoft Digital Marker) table exists in your BIOS. This table contains the Windows product key.
    2. Use OA3Tool: Utilize the OA3Tool to validate the DPK (Digital Product Key) against the installed Windows edition. You can run the following commands:
      • OA3TOOL /Validate to check if the MSDM table is present and correctly formatted.
      • OA3TOOL /CheckEdition to verify that the injected DPK matches the target Windows edition.
    3. Activation Process: If the product key is correctly injected into the firmware, Windows should automatically activate when the device comes online. If you encounter issues, consider reaching out to Microsoft support for further assistance.

    If you are still facing problems with the activation watermark, ensure that your system is connected to the internet and try activating Windows again after running these checks.
