Hi Ellen,
I'm Amr, an independent advisor.
Did you get your Windows 10 pro key and you are asking how to install the pro version? or are you asking how to upgrade to Pro without installing Windows?
You can upgrade your Windows without installing, please refer to this link to guide you how

If you want to install Windows 10 Pro
Click this link:
https://www.microsoft.com/en-us/software-downlo...
to download the Media Creation Tool (Click on Download Tool Now), with that, you can download the latest Windows 10 ISO (Select Create Installation Media for Another PC), you can create a bootable USB flash drive (min 8GB) using that tool
Then, Boot your PC from the Installation Media you just created (change Boot Order in your BIOS) to begin installing Windows 10
During the installation process, he will ask for a product key put it and continue installing.
Best regard
Amr
