Windows Vista build 5259

Windows Vista build 5259 is a pre-Beta 2 build of Windows Vista.

Setup
Once again, the setup interface has been changed massively - mostly being one of the biggest changes yet. A new aurora wallpaper has been introduced, replacing the old bluish wallpaper with the Windows logo on the top-left. The setup autorun has also slightly decreased in length, and now uses a fade effect as well. It also introduces a new logo found in later releases of Windows, including Windows 7, however it is slightly stretched. The colors of the buttons also don't match slightly with the autorun background. Once choosing to install Windows, the same old progress bar will be left mostly untouched (asides from the bar being split between sections and now accurately increasing in size), however the main part of setup itself is now based inside an Aero-themed window mockup. However, many things (such as the buttons and text) aren't positioned correctly, and the Windows logo on the top-left is also stretched. The entire font is also different.

For the pages itself, the product key page now has a new option, prompting for whether you'd like Windows to automatically be activated upon reaching the desktop. The disk partitioning section of setup is also re-organized slightly, and the disk icon may show a 4-bit Windows XP logo.

New features and changes

 * The most important change here is the new Start orb and the slightly redesigned start menu which will stay similar all the way up to Windows 7 (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.


 * 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.
 * Option to use USB drives as a virtual RAM (Super Fetch).
 * "Publish to RSS" is removed in Windows Calendar.
 * "Publish to RSS" is removed in Windows Calendar.
