Draft:Windows Longhorn Home

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, known now as File 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.

Windows Longhorn Home was a Home edition of Windows Longhorn, that was supposed to exist. It was cancelled afterwards.
