How do I transfer my product key from my old computer to a new gaming build?

So I bought windows 8 for a new computer I bought that had windows 7 on it before. I then decided to build a gaming computer a few months later and now want to use my old product key or get another product key for my gaming build. If there is any way to do this can someone please get back to me ASAP.

Answer

You can't use Windows 8 Upgrade on a blank partition.

 

To install an upgrade version of Windows 8, you must already have Windows 7, Windows Vista, or Windows XP installed on your PC.

If you formatted the drive before the upgrade version of Windows 8 was installed, you won't be able to use your upgrade product key to activate Windows 8. To activate Windows 8, you'll need to install your previous version of Windows, and then reinstall Windows 8. For help with the activation process, contact support.

 

Still, look into the following:
