Windows Longhorn build 4067
|Build of Windows Longhorn|
Windows Longhorn build 4067 is a Milestone 7 build of Windows Longhorn. It was shown during WinHEC 2004 when Jim Allchin used it to demonstrate the then-new Longhorn Display Driver Model (later known as the "Windows Display Driver Model").
A presentation photograph featuring two screenshots of this build and a screenshot of build 4069 was first shared by LucasB (also known as ComputerHunter) on 26 May 2021 — a high resolution version of the two screenshots were later leaked by ReflectiaX (aka BetaCollector) on the same day.
