    Hi there,

    Error 0xC004C003 occurs when a licensing code component tries to access a registry hive without proper access. The resulting access denied error causes the product key not to be extracted correctly.

    You can try offline updates using a generic key. To activate with the Pro Product Key, you must first go offline using Airplane Mode in the Action Center, insert the default Generic Version key to change to Pro Version.

    Then go back online and insert the Pro Product Key in Settings > Update & Security > Activation > Change Product Key to Activate.

    Windows 10 pro generic key
