Windows "Longhorn" build 4093, with a build tag of 4093.main.040819-1215, is the last winmain compile of the original "Longhorn" line (based on the Server 2003 RC1 code-base) before development was reset. It was leaked on August 28, 2006, shortly after the closure of OSBetaArchive, and was labeled a farewell release. This build is highly unstable.
