Windows Vista build 5342 (vbl ux partners winapps)

This build isn't leaked, but there is a better known compile of it which has the build string 5342.2.winmain_idx04.060321-1730, dated a few days after this one. Build 5342.2 is not overly different from 5308, note, and the screenshot used in the build infobox is of that compile.
