naming of Windows 7

Microsoft said Windows 7 is named because it is the 7th generation of Windows OS. Can anyone still recall all the previous six generations. It's not difficult. I can say they were Windows 3, Windows 95, Windows 98, Windows 2000, Windows XP, Windows Vista.

Still history again, TCP/IP stack was added starting from Windows 95. IPv6 stack was available in Windows 2000, Windows XP and Windows Vista but Windows 2000 and Windows XP require users to install and enabled it. For Vista, IPv6 is enabled by default. Of course, as Windows 7 is an improvement over Windows Vista, all IPv6 features are retained.
