New features and changes[edit | edit source]

User interface[edit | edit source]

The watermark now states Beta 2 rather than Beta 1.
The Avalon/Indigo and supplemental drivers shortcuts have been removed. These however will remain when upgrading from build 5112.

Flip3D[edit | edit source]

This is the first available post-reset build to reintroduce what was known as Flip3D after being removed in later pre-reset builds. It contains similar functionality to Alt+Tab ↹, however it now utilizes the Desktop Window Manager in this build and creates a 3D flipping effect in between all of the applications currently open, thus the name "Flip3D". Flip3D can be used via pressing ⊞ Win+Spacebar , rather than ⊞ Win+Tab ↹ which was used in later builds or Alt+Tab ↹ that was used in pre-reset builds. Also, Flip3D now utilizes animations, unlike in pre-reset builds.

AutoPlay[edit | edit source]

AutoPlay now has more functions compared to build 5112. For example, there is now a checkbox, which invokes, that this option should always been done for this type of media. Additionally, at the bottom, a link has been added (Set AutoPlay defaults), which redirects to the AutoPlay settings.

Applications[edit | edit source]

Windows Sidebar[edit | edit source]

This build is the first post-reset build of Windows Vista to reintroduce Windows Sidebar. Rather than working inside explorer.exe (which caused memory leaks), this time the Sidebar runs in its own process. In this build, the Sidebar doesn't start automatically upon booting up.

Gadgets are mentioned as "Parts" inside the user folder. There are four gadgets: Clock, RSS Feed, Photo Slideshow and Search.

Windows Media Center[edit | edit source]

Windows Media Center and its services have been introduced in this build's Home Premium and Ultimate SKUs, and it features a drastically different look compared to the one featured in Windows XP Media Center Edition 2005, but it still identifies the OS as such in the About page. It is also included on the taskbar by default.

Windows Photo Library[edit | edit source]

This build also includes the earliest version of Windows Photo Gallery, called Windows Photo Library. It's based on Microsoft Digital Image Library.
