Windows Vista build 5098

Windows "Longhorn" 5098.winmain beta1.050628-1740 is among the last builds compiled before the Beta 1 stage of Windows Vista. By this point, Microsoft implemented a substantial amount of features originally slated for Windows "Longhorn", signifying the end of the Omega-13 stage.

This build marks the beginning of the beta 1 stage. By this build it looks like final Windows Vista and quite similar to 5112, although it still is called Windows 'Longhorn'. This build also has the 5112-style setup. It cannot upgrade to 5112 because build 5099 or higher is required to do so. Sadly this build remains unleaked. Paul Thurrot used screenshots of this build in his review of Vista Beta 1.

This build includes the Windows Aero visual style, WDDM video drivers, Start menu updates, and the Games Explorer.
