Windows Vista build 5259

Windows Vista build 5259 is a pre-Beta 2 build of Windows Vista, which was shared online along with a recompile on or before 30 November 2005.

Setup
The setup interface has been changed in this build, now using a window in the middle of the screen with a fake Aero border and Aero buttons, but the title bar is not transparent. A new aurora background for the Preinstallation Environment, first seen in build 5252, has been introduced in place of the older blue Windows logo graphic. An option to automatically activate Windows upon finishing setup has been added to the product key page. The disk partitioning section has also been slightly reorganized.

The second phase has been updated with the new wallpaper as well, however, it still retains the general look of the previous setup design iteration. The most notable change is that the progress bar in the bottom of the screen has been replaced with one similar to the first phase with numbers and labels marking each stage of the installation process.

This is also the first post-reset build with a WIM-based setup to feature an Out-of-box experience. Compared to the Windows XP version, the OOBE uses the Aero Wizard interface and includes pages for determining information that would have been determined during the second phase of Windows XP setup. The version included with this build is already very reminiscent of the version that shipped with RTM, although it uses the Tahoma font instead of Segoe UI and some graphical glitches are present.

The autorun program has also been updated with a new version of the Windows flag, however, it is vertically stretched in this build.

Despite of the introduction of the new logo, the icon shown on the title bars of autorun, setup and OOBE is still the older one from 2001 and horizontally stretched in autorun and setup.

This is the earliest available build to store the minimum build number required for upgrading in.
