Windows Vista build 5252

Windows Vista build 5252 is an unleaked pre-Beta 2 build of Windows Vista. This build was showcased in a blog from Chinese IT consumption portal Yesky. It is the last known build to feature the older Aero design from build 5231.

Changes

 * This build notably features the Start orb with the colored Windows flag, previously seen in build 5212 (vbl_ux_dev_checkin), but with a lighter shade of blue. However, classic theme still uses white logo.
 * The background used in setup has been changed to the aurora found in the RTM build, but the older setup layout was retained.
 * This build includes the new start menu, previously seen in build 5221 (vbl_ux_dev_checkin_gamesux)
 * This build includes a new desktop wallpaper, changing the one used in previous builds since 5054.
 * This build changes the Windows Explorer banner background from the static blue used in 5098 to 5231 to a green gradient.
 * This build also marks the first appearance of both Windows AntiSpyware (later renamed to Windows Defender) and Windows Mail (the successor to Outlook Express).
