Installing Windows 10 for a New PC on a USB

[JSlate5]

I'm building a PC from scratch and I'm not adding an optical drive to the build to save as much money as possible. How do I install Windows 10 with a USB? Do I need to purchase a special digital product key so I don't buy a CD install of Windows for a computer with no CD drive?

Create your own USB install here:

Use the license key that came with your DVD.

You'll need a USB stick of at least 5GB, and it will be wiped when you create it. So don't have anything on it you wish to keep.
