Hi,

You don't need an activation key as the Windows 10 on your PC was digitally registered with Microsoft when it was activated. If you need the Windows 10 media then download Windows 10 from Microsoft.

The "trick" here is on the installation screen that asks for the 25-character product-key.

On that screen, click "I do not have one".

The installation of Windows will continue.

The first time that you connect to the Internet, your "digital entitlement" (obtained when you first installed Windows 10 on the same hardware) will be leveraged, and Windows will "activate", at no cost to you.
