Microsoft Windows Vista, 6.0.4053.0

There is not much difference between the PDC2003 Build and this one, this one does however have a ''File a Longhorn Bug'' link on the desktop and the notifications on the desktop work again, they were missing in 4051.

VoteNow
Included in this build is an internal application named VoteNow.exe it display's a message so that the employees using that build can vote the build after some time (~4 hours).

It seems that the Desktop Notification that should display with 'You have been using this Longhorn build for a few hours now. By using the Vote Now button below, you can vote to let us know what you think of it. To learn more, click this text. is broken in this build, due to it doesn't display after the set amount of time.
