Windows Longhorn

"Longhorn" was the codename for planned successor of Windows XP. The project was cancelled, and replaced with a new project with similar codename - Longhorn Omega-13, that was renamed to Vista that became the real successor of XP. Early Vista's builds were reffered as just Longhorn for most of the time and those two projects were often mistaken.
