Windows Vista build 5231 (winmain)

Windows Vista build 5231 (winmain) is a pre-Beta 2 build of Windows Vista, which was shared online in late November 2005 only in the x86 architecture.

Setup
Setup has received minor uplifts compared to previous builds of Vista. For starters, the fonts used in both the first section of setup and the hardware portion have been changed. There is also a new fading animation whilst switching between pages in the first section of setup. The "your installation summary" page has also been removed, and its subpages are now just generic pages shown after going past the upgrade page. The progress bar on the hardware portion stage of setup now increases in size depending on how far you actually get with setup. The product key stage now lets the user choose to activate Windows when the user's online.

This build is the first post-reset build of Windows Vista which allows an upgrade from Windows 2000 SP4 and Windows XP. Although it requires build 5223 to upgrade from earlier Vista builds, this can be bypassed by setting the compatibility option for  to "Windows XP".

DWM
The Aero theme when DWM is initialized has received a few minor uplifts. The program buttons on the top-right are slightly lighter when the cursor isn't hovering over them. A transitioning effect is also utilized if moving your cursor on top of the buttons, and the glowing effect now mostly resembles that of RTM. These changes were first seen in the vbl_wcp_avalon compile of build 5221.

File differences
The following files have been introduced or removed compared to build 5219:

Installation

 * This build will BSOD during the setup on QEMU and modern versions of VMware. Using either VirtualBox or VMware with either 5.x or 6.x hardware compatibility is recommended.
 * The  text when launching setup on Windows appears to be condensed on higher resolutions such as 1920x1080.

Taskbar

 * If DWM is enabled, the font on the Start button is bolder than usual.
 * If the theme is set to Windows Classic and then reverted to Aero, parts of a taskbar reminiscent of the one seen in build 5048 may be seen.

Migration Wizard
The following bugs are internal known issues found in  in the sources folder.


 * Currently, only disconnected migration is supported.
 * The Drive Exclusion page has no effect on the items to be migrated.
 * To increase performance on machines with razzle environments, you can have the docs agent skip scanning all drives (which can take several minutes on some machines) by setting the environment variable  before running the wizard.
