Does anyone know if windows 7 installer will allow an upgrade from build to build? Is Microsoft releasing updates as windows 7 is developed to keep up with the builds? I have been using it since the first leaked copy from the PDC in October and would just like to upgrade? I'm new here but not new to fourms, and could not find any information on this here. It already a very stable os thus far, as it should be since it was built upon vista and most of the kinks have been worked out. Thanks!
