Windows 10: Upgrading to a new mother board

I purchased a prebuilt gaming PC.. I am going to be upgrading to a RTX 2080ti and adding more ram to it. eventually I am going to Dual 2080ti but my motherboard only supports 1 video card ASUS Prime B450. I am going to purchase a new mother board that supports multiple GPU's. My question is.. will I have to purchase a whole new version of windows for the new mother board?

Replacing Mother Board

I need to replace my mother board. I have purchased the identical replacement. I want replace the mother board and use the same old Processor. Processor is i7 6700K and the motherboard is ASUS Z170. Is it possible to replace the Mother board without re installing
the Windows and software.

Thank you
