Windows Longhorn build 4093 is the last 'main' compile of the original "Longhorn" project (based on the Server 2003 RC1 code-base) before development was reset with build 3790.1232. This build was leaked on 28 August 2006, shortly after the closure of the original OSBetaArchive, and was labeled a farewell release. It was the last pre-reset "Longhorn" build to be leaked, and one of the last to be compiled.

Many applications and features are unstable works-in-progress, and might not function as intended. However, most working features and applications can be launched using the Run command and certain features like WordPad and the Windows Classic theme has been fixed. The development reset began a mere four hours and fifteen minutes after the compilation of this build, at 16:29 (although many teams had already been working with the new codebase since at least 3 August 2004). Development moved to a new code base, which eventually became Windows Vista.
