Need to run Windows

After being able to avoid this for so many years, I need to install VM Fusion and a copy of Windows on my MacBook Pro Retina.



So the question is? What version of Windows? I see TigerDirect has both 32 bit and 64 bit versions. Both 8.1 and 7. Some are OEM products.



Has anyone been through this recently?:)
