Windows 7

I've been running the 64-bit version of Microsoft Windows 7 Ultimate for some time now and it works well. Windows 7 is what Vista should have been. I have a beast of a desktop computer at home (AMD dual core that supports virtualization), 8 GB of physical memory, and 750 GB of disk space among other features. I ran the 64-bit version of Vista Ultimate on this same computer and it sucked the life out of it. I don't know what Microsoft was thinking with Vista but they've fixed the problem now with Windows 7. Props to Microsoft for getting it right.
