Simply put the DVD in the drive and run setup. It will detect the key:

The good news is that you no longer have to worry about it fading or getting scratched. The 5x5 key is embedded in the BIOS. Therefore all I had to do in order to install a fresh clean copy of Windows 8 was attach an external DVD drive, boot from the retail DVD, and run setup. As soon as I connected to the internet, the machine activated. It never asked me for a key. No fuss!!!
