Question

I am a .net and java deloper. I have an MSDN subscription with access to all editions of the Windows 7 operating system. I am going with a 64 bit installation. Which edition of Windows 7 should I install on my development PC: Professional, Ultimate, Enterprise, Enterprise N, etc.? Thanks in advance.

Answer 1

Put Ultimate on the box and run the others in virtual machines.

Answer 2

If you have access to all versions, I see no reason not to install Ultimate.
