Windows Longhorn build 4044

Windows Longhorn build 4044 is an unleaked Milestone 7 build of Windows Longhorn. This build is very similar to build 4042. This build uses a different "About Windows" dialog which is seen in later builds and a new shortcut on the desktop, "Hang Reporting Tool". This build was first seen in a screenshot at PDC 2003 during the Avalon Graphics and Media (Part 2): Using Graphics, Animation and Composition in Your Applications session (CLI341) by Greg Schechter presentation to demonstrate the power of XAML in Windows. Since then, a couple more screenshots of this build have been leaked.
