I used the same username for the admin account ("Blaize"). When I went to c:/documents and settings, there was now a Blaize, and a Blaize.LOCAL
Above is the give away. The way i see it. On install you have the option to set a Administrators Password You do not get to choose a different name.

Later when the os is installed you are asked to enter user names and passwords and if you would like to make files pertaining to these users private. Assuming you do nothing els at this stage you will continue to windows. From there you can change account types etc from within the control panel. If you do not change account types, by default every user entered at the first start of windows will be an admin.

However there is a Hidden The Administrastors account. To access this you nead to either press f8 on bootup and boot to a diagnostic option or boot from your win xp cd. Either of these options will give you the option to log in as The Administratoror another user. If a password is set at install for The Adinistrator and you log into that account you have complete control of the system. Period.
