windows 8.1 key help

[Kean]

So I'm going to build a new computer and am planning to purchase the win8.1 key from 

 

https://www.g2a.com/windows-8-professional-32-64-bit-cd-key-global.html

 

Would anyone be able to guide me on where I can download a genuine clean iso file to mount onto a USB to install

the window on the newly (to be built) machine?
