Windows 10: Pay for the installation of Windows 10 on my computer

Hello. I want to install Windows 10 from the official website, https://www.microsoft.com/en-us/software-download/windows10 but it says here that "you will first need a license to install Windows 10". Does this mean that I will not be able to install Windows 10 on my computer without the specified license? Or does it mean that I first need to pay for a license to install Windows 10, and then, after I install Windows 10 on my computer, I also need to pay for activating Windows 10 on my computer? It turns out that I pay twice?

Installing Windows 10 on New PC?

I'm going to be building a new PC on Christmas and want to install Windows 10 on it. I have Windows 10 on my current PC, which I installed upgrading from 8.1 with the files on a USB. How do I go about installing a clean copy of Windows 10 on this new PC? I think I recall something about installing it once makes Microsoft recognize your hardware, but since this will be a PC I'm not sure what steps I need to take. Do I need to go 8.1 -> 10 or is there a method of going directly to 10?
