Windows Vista build 5231 (winmain)

Windows Vista build 5231 (winmain) is a pre-Beta 2 build of Windows Vista, which was uploaded 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.
