To enable clean installation of Windows 10 on devices that upgraded and activated online using the free upgrade offer

1. You will be able to download and create installation media on a USB drive or DVD for the appropriate Windows 10 Edition
2. You will be able to skip entering the product key during Windows 10 Setup. Windows 10 will activate online automatically on such devices. The skip option is only available when booting from media and launching setup

How on earth do I get the installation media???
