What version are you using?
Not for sure if there is an option to do that when Windows starts, but the easiest way to do this is create a shortcut link of altbinz.exe from the installed directory and drop it into the c:\Documents and Settings\All Users\Start Menu\Programs\Startup Directory
Or of you don't want all users to have it start up you can also use c:\Documents and Settings\$USER NAME\Start Menu\Programs\Startup Directory (Where $USER NAME is you Logon name to windows.
Hope this helps...
