'''''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.
'''''Longhorn''''' was the codename for the planned successor of [[Windows XP]].


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]].

Development was reset, but post-reset builds continued to use the "Longhorn" codename until the final name, [[Windows Vista]], was announced on 22 July 2005.

{{Quotation|The mechanics of doing this are mind-numbing. [...] We have a main branch of code for the current Windows version, and that branch becomes the source base for hot-fixes and the next service pack. Once we spit out a service pack, that becomes a branch and now we have two branches we have to test for hot-fixes and service packs. We can't tell customers to install, say, SP1 and then do this hot-fix. And this is going on for every [Windows] release, so some have 2 or 3 service packs, many hot-fixes, and many security fixes. Every one of these is a managed collection of 50 million lines of code. It's a pretty big accounting issue.|Mark Lucovsky|Paul Thurrott's Windows Server 2003: The Road To Gold Part Two: Developing Windows|<ref name = "server2003"/>}}

Windows Longhorn
Windows Longhorn Logo.png
Windows "Longhorn"
Codename
Preliminary name		 Longhorn
Kernel version NT 6.0
CPU architecture x86, x64, IA-64
Release date N/A
Support end N/A
Preceded by Windows XP
Succeeded by Windows Vista

Longhorn was the codename for the planned successor of Windows XP.

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.

Development was reset, but post-reset builds continued to use the "Longhorn" codename until the final name, Windows Vista, was announced on 22 July 2005.

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]

Codebase

The popular belief is that pre-reset "Longhorn" builds are based on Windows XP. This was likely spurred by Paul Thurrott's statement on his review of build 5048: "The problem, I was told recently, was that the underpinnings of Longhorn--then based on the Windows XP code base--were struggling under the weight of all of the technologies that Microsoft planed to implement in this release."[6] However, pre-reset "Longhorn" builds are based, not on XP, but on Windows Server 2003 code.[5] The xpclient release branch, dedicated to XP, spun off from the main branch in 2001. The main branch continued to compile Server 2003 builds at the 3xxx range, such as build 3663 (release candidate 1), until the dnsrv branch dedicated to Server 2003 spun off from the main branch in 2002. After that, the main branch began compiling Longhorn builds.[7]

Mark Lucovsky, Microsoft Distinguished Engineer and Windows Server Architect, explained to Thurrott in 2003:

The mechanics of doing this are mind-numbing. [...] We have a main branch of code for the current Windows version, and that branch becomes the source base for hot-fixes and the next service pack. Once we spit out a service pack, that becomes a branch and now we have two branches we have to test for hot-fixes and service packs. We can't tell customers to install, say, SP1 and then do this hot-fix. And this is going on for every [Windows] release, so some have 2 or 3 service packs, many hot-fixes, and many security fixes. Every one of these is a managed collection of 50 million lines of code. It's a pretty big accounting issue.

Logos

Several different logos were created throughout the development of "Longhorn". Early builds used 2D and 3D representations of a longhorn bull; later builds included white or glass versions of the Windows flag.

Implementation of concepts

Twitter user Lucas Brooks (mswin_bat) found that porting the private Milestone 7 Aero theme to a Milestone 5 build like 4017 enables the striped sidebar shown in a demo.[10]
