Windows Vista/6.0.5001.winmain.040927-1610

Windows "Longhorn" build 5001 (with a build tag of 6.0.5001.winmain.040927-1610), is among the first builds of Windows Vista to be compiled after the development reset of Windows "Longhorn".

This build includes updates to the operating system branding, but because the build was compiled so early after the development reset, there are only a few noticeable differences from Windows XP and Windows Server 2003. It is notably one of the few builds to include a Longhorn bull wallpaper which is also included in 5048's help pane. The screenshots' authenticity has been disputed many times in the past. This build was leaked on January 23, 2020, following Grabberslasher leaking all of his builds from his blog. New Longhorn Builds for a new decade
