Russian website, Torrents.ru posts that Windows 7 build 7022 (7022.winmain.090115-1850) has leaked to the internet. The full build number shows that it is at least a month old, and therefore most likely does not contain the new UAC enhancements that we discussed earlier. They provide four new screenshots, showing minor UI changes.
Some of the new things include IE8 being updated to release candidate 1 and a new design to the media player buttons. The side of explorer also appears to have a redesign.
