I'm a guy who loves Windows OSes and I'm currently dualbooting Windows 7 Professional x64 and Server 2012 R2 x64x, though later I'll probably replace 2012 R2 with 8.1 Enterprise and I'll add Windows 10 LTSC making it a tripleboot. Unfortunately Vista isn't compatible with Intel 5th gen Broadwell CPUs so I can't use it.
