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.

Changes
This build notably features the older Aero design from build 5231 and the Start orb previously seen in build 5212 (vbl_ux_dev_checkin), but with a lighter shade of blue. 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 also marks the first appearance of both Windows AntiSpyware (later renamed to Windows Defender) and Windows Mail (the successor to Outlook Express).
