Windows Vista build 5098

Windows "Longhorn" build 5098 is one of the last builds compiled before the Beta 1 stage of Windows Vista. By this point, Microsoft implemented a substantial amount of features originally planned for Windows "Longhorn", thus ending the Omega-13 milestone.

This build marks the beginning of the beta 1 stage. This build looks 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. Paul Thurrott used screenshots of this build in his review of Vista Beta 1, and UX.Unleaked also has a few images of this build available. This build leaked on 2020-01-23.

This build updated the Windows Aero, and introduced the Games Explorer.
