The project was reset and replaced with a new project - ''Longhorn Omega-13'' which was later renamed [[Windows Vista|Windows Vista]]. Early builds of Windows Vista were often referred to as "Longhorn", causing confusion.


One of the original - and largest - changes is that, with "Longhorn", the .NET Framework would be integrated into the core Windows platform, deprecating the traditional Win32 API. During development, portions of the operating system were rewritten, causing memory leaks and instability, particularly in [[Windows Explorer]].

Contrary to popular belief, most of the early builds of "Longhorn" are not based on Windows XP, but [[Windows Server 2003|Windows Server 2003]] (Build 3663) Release Candidate code.

"Longhorn" was chosen as the codename for the operating system to represent its initial status as an internim release between Windows XP (codenamed "Whistler") and Windows "Blackcomb".

Windows Longhorn
Windows Longhorn Logo.png
Codename
Preliminary name
Longhorn
Kernel version NT 6.0
CPU architecture x86, x64, IA-64
Preceded by Windows XP
Succeeded by Windows Vista

Longhorn was the codename for the planned successor of Windows XP. The project was reset and replaced with a new project - Longhorn Omega-13 which was later renamed Windows Vista. Early builds of Windows Vista were often referred to as "Longhorn", causing confusion.

One of the original - and largest - changes is that, with "Longhorn", the .NET Framework would be integrated into the core Windows platform, deprecating the traditional Win32 API. During development, portions of the operating system were rewritten, causing memory leaks and instability, particularly in Windows Explorer.

Contrary to popular belief, most of the early builds of "Longhorn" are not based on Windows XP, but Windows Server 2003 (Build 3663) Release Candidate code.

History

Codename

"Longhorn" was chosen as the codename for the operating system to represent its initial status as an internim release between Windows XP (codenamed "Whistler") and "Blackcomb". Whistler and Blackcomb are names of mountains in British Columbia, Canada,[1][2] and Longhorn is the name of a saloon located in between the two mountains, representing the operating system's initial status as an internim release between the two products.[3] Bill Gates would later state that this choice for a codename of the operating system was "a bit random".[4]
