So I am in the process of building my first PC and am choosing an OS. I am leaning toward Windows 8 OEM to save a bit of money, but might want to upgrade once the updates stop in 2023. I know that when switching out a mobo with an OEM licence, a new licence has to be purchased, but do I have to switch out my mobo when I upgrade the OS? I have no idea if it's bound in the same way and would rather be safe than sorry.
