Am I the only person who just read it as "I want the system to automatically log me on" ? In which case XP has a user2 control panel that you can load which lets you do it - all this about booting CD's and the like when you can just put it into the default OS?
Of course if I'm on the wrong track, then I retract this, but seriously people, over complicate the process?!
Edit: And yes I am aware that whatever question was asked was asked 10 months ago
