Esvan360 :
I'm upgrading my PC from a Gigabyte GA-78LMT-USB3 and an AMD FX-6300 to an ASRock B450M PRO4 and a Ryzen 5 2600. I have windows 10 OEM installed on my 120GB SSD, and it's linked to my microsoft account. I also have a 1TB hard drive where all my games and programs are stored. I want to do a clean install of Windows 10 on my SSD to avoid conflicts in the future but I'm not really sure how to do that. Can someone walk me through how to do this?
Where, specifically, did the Win 10 license come from?
The "OEM" may not be a concern.
For the OS activation, read and do this before you change any parts:

After that, you may indeed need to do a clean install of the OS on your SSD.

Steam games on your secondary drive can probably be reused, but all your other applications will need to be reinstalled.
