Windows Vista build 5001

Windows "Longhorn" build 5001 (with a build tag of 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. It also replaces the "XP" in winver banners with "lh".
