No impact on Windows. Changing your CPU won't affect it unless you modify system settings or drivers.

Your setup should work fine with the new components. Just ensure the motherboard supports the i5 6400 and DDR4 RAM, and that the new board is compatible with Windows 10.
It could work, though I think Windows leaves some kind of mark on the parts. Changing components occasionally might disrupt activation.
No, altering motherboards won't fix the issue—just update the drivers. I moved my SSD from an i7 2600 to a new i5 6500 to see if it was failing. It started up properly.
I think it's different for everybody, so far (over 2 mobo changes) Windows doesn't boot properly if you plug in a boot drive that was from the old mobo. I always have to reinstall Windows. Oh yeah, also Windows 10 has been known to deactivate if a drastic change in components happens.
Only if you're using an OEM copy of Windows 10, since it's connected to your motherboard.
