Windows Vista build 5112

Build 5112 was officially released on July 27th, 2005. As such, it was one of the earliest builds of Beta 1 compiled, and one of the earliest which was widely available. At the point of compilation, Microsoft had decided on Windows Vista being the final name of the operating system, hoping to boost the image and perception of the product itself among users.

Jim Allchin himself expressed his feelings for the final name, stating: "'Vista' creates the right imagery for the new product capabilities and inspires the imagination with all the possibilities of what can be done with Windows – making people’s passions come alive."

However, the name Longhorn was still used in numerous areas, such as within the About Windows dialog box.

In comparison with Build 5048, this build was a much more significant advancement in regard to introducing new user interface features. The Explorer shell had seen significant changes, including virtual folders, a new search interface, numerous new high resolution icons, and a redesigned toolbar.

This build also introduced many other features that were planned for Windows Longhorn, including the new networking and audio subsystems, and the .NET Framework 3.0 (still referred to as WinFX) which was nearly complete at the time.
