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. The window background has also been changed to a solid dark blue color.

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.

Windows Media Center
Windows Media Center has been updated quite a fair bit, now containing a much different layout.

Windows Digital Gallery has been renamed to Windows Photo Gallery with minor updates to it. Also, several features left from Digital Image Library have been removed.

Windows Calendar
"Publish to RSS" has been removed from Windows Calendar.

File Explorer
In File Explorer, many icons have been replaced and the ribbon color has been changed to a static blue-green gradient. Also with this build and later on, system folders are no longer hidden by default. With this, the functionality to hide/show system folders have been removed from Folder Properties as well. Also, new search filters have been introduced.

Control Panel

 * The gradient on the left sidebar has been changed to dark green to light green with the addition of the Windows logo as well.

User interface
Hardware-accelerated Aero theme now resembles its RTM version more, with things such as buttons and drop-down menus now being updated to a less glossy style. Flip 3D also resembles its RTM version. The taskbar and start menu have received major updates, with the taskbar resembling that of the RTM as well. The taskbar now has a new icon in its quick launch section that was first seen in build 5252, which essentially initializes Flip 3D, which means it isn't functional without DWM being utilized. The start menu is closer to resembling that of the RTM, but it still has a few differences. There is also now an option to change the color of the Aero theme.

Removed features
Most of the color schemes for the Windows Classic theme have been removed, except for the High Contrast ones, Windows Standard and Windows Classic.

Bugs

 * Certain applications such as Device Manager are not accessible via the Run prompt. In this case, an alternative route is Control Panel -> System -> Hardware -> Device Manager.
 * This build tends to have stability issues, and can easily crash upon simple tasks, such as installing drivers and opening up applications. At worst, bluescreens can also occur.
 * The CPU may not be shown correctly in system properties.
 * Even if the machine does not have a floppy drive, a button for it may appear in File Explorer anyway.
 * Explorer may randomly crash at times.
 * System Restore cannot be used in this build as it will fail to create and restore with error.

Installation

 * On some devices and virtual machines, the setup cannot partition the hard drive, requiring the usage of DiskPart. After using Diskpart to partition the hard drive, you must then restart the machine.

Build 4033

 * It is not possible to install or upgrade this build from build 4033 due to an assertion error.

Build 5000/5001

 * It is also not possible to install or upgrade this build from build 5000 and build 5001 due to setup.exe crashing.
