Windows Longhorn

Windows Longhorn is the codename for the version of Windows that eventually became Windows Vista. Although, Windows Longhorn had 2 phases of development, the first phase ran through several builds and milestones that were based on Windows XP. However, near the end of the first phase of development using XP as a base proved to be very unstable and they restarted development by using Windows Server 2003 as a base.
