Upgrading Motherboard and CPU

I bought a default Lenovo K450 a few years back that came with Windows 8 preinstalled. Well over the past few months I've upgraded the PSU, GPU, and moved too an SSD without much of a hassle since I was using the same motherboard and CPU. Well, I'm moving
too a whole new upgrade and changing the case, motherboard, CPU, and adding a network card. My question is, once I've changed out all of the parts, will I need to reinstall Windows 8, or can I just install Windows 10 again like normal and follow the steps
with customer support to establish the legitimacy of my previous Windows OS? I have the OEM and Product Key.

Can I switch motherboard and cpu and use the old SSD?

I want to upgrade my motherboard, CPU and RAM. I recently upgraded my HDD to a new SSD and did a clean install of W7 then upgraded to W10. Will I be able to just install the new hardware and have Windows boot from the SSD as is? Or will I need to reinstall
W7 then upgrade to W10 again? Would Microsoft allow me to upgrade again for free?
