Windows Vista build 5259

Windows Vista build 5259 is a pre-Beta 2 build of Windows Vista. This build is the first official build to include the Start orb (although it was also found in a few earlier builds from the vbl_ux_dev_checkin lab such as 5212 and 5223, and from the winmain lab such as 5252).

Windows Antispyware is now added, and the setup UI is revamped, including a new Aurora background as well as a new OOBE. There's now an option to change the Aero Glass color.

Installation
On some devices and virtual machines, the setup cannot partition the hard drive. If this happens to you, please partition the disk in a different build's PE.
