the shutdown event tracker is enabled by default in server 2003 it hardly constitutes as an easter egg, its just so that windows knows why you shut it down
logon, yes '03 uses the classic logon screen and xp uses the new logonui screen boot, yes the progress bar is a shade of grey instead of blue / green the main branding bmp is also predictably different desktop, kinda by default '03 doesn't use themes so you're in classic mode the start menu default places and pinned items are also different my computer doesn't show my documents or common tasks and the details view is the global default overall, yes there are quite a few changes hardware acceleration is disabled drive mounting is disabled ieharden and shutdown event tracker are both enabled need any specifics ? just ask
all that you really need in an xp icon is 32bit versions of the 16x16, 24x24, 32x32 and 48x48 if you're using large icons mode the only time you need to go into lower bit versions are when your graphics card cannot support them.
i've been trying to do this for some time (glad i'm not the only one to be honest) setting a mixed case value in winnt.sif [unattended] TargetPath= always produces a version in capitals
media fire used to be one of the best, unlimited file size, no wait times, minimal adverts, excellent reliability but they seem to be getting worse with every upgrade now your limit is 100MB, popups and banner ads and its rarely ever online
