Internet Explorer 6.05
From BetaArchive Wiki
Internet Explorer 6.05.4053, running on Longhorn 4053.main
Internet Explorer 6.05 came installed with pre-reset Longhorn builds. Internet Explorer 6.05 has went through many changes throughout Longhorn development. It contained download manager (however broken in a lot of builds). In later builds the GUI was integrated with the new extended title bar (same way as Explorer's windows) and allowed extended Aero as well.
