In setting up Windows XP Home for my niece, I ran into something really weird. When I got to the Add Usernames part of the installation and typed in her name--Sammy--it wouldn't go through. The message I got was something like this: 'Names must not be equal to "SAMMY", "Administrator", or "Guest".' Interestingly, Setup gave no resistance when I changed the username to "SAM".Anyway, my niece is five years old and insists on "Sammy" as her username. So I have two questions: what does the name "Sammy" mean to Windows XP, and why can't we use it?
