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 settings" 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 the user actually gets 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".

User Interface

 * The tray icon for Network Connections has been updated since build 5215.
 * A new volume control app that was first seen in build 5209. It allows the volume to be set independently.
 * The link to the Avalon/Indigo HTML document on the desktop has been removed.

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.
