I'm running a Windows 10 free upgrade, the previous license is a Windows 8 retail version. I'm looking to upgrade my motherboard and don't know how to start. If I were to do a reinstall of Windows 10, would I have to do it prior or after peicing everything in? Would I be able get an installation file from Microsoft (I don't know where the original disk is). I'm not concerned on losing any files, I would just like to make sure there are no hardware conflictions.
