Table showing internal version numbers of the various versions of the Microsoft Windows kernel. The names in bold are those used by Microsoft to market the releases.
Note that to reach "Windows 7", Microsoft are grouping previous releases by their internal version number, but are saying that Windows 7 will be a major release of Windows, without being a major version of the kernel and underlying API.
