Windows Longhorn
From Conservapedia
Windows Longhorn was the code name for both a canceled version of Windows and Windows Vista. The first developer builds were compiled sometime around 2002–2003, however, in August of 2004, Microsoft announced that Windows Longhorn would be scrapped, and a new project would begin under the "Longhorn" name.[1] This operating system used the NT 6.0 kernel, which is the same version which was later used by Windows Vista and Windows 7.[2]
