|What type of Account is yours, Admin. or Limited ?????|
XP requires that there always be an Admin. account.
Back when you started the XP computer for the first time ever,
you were shown a screen where you enter every name of a person that may be using XP. Each name is entered under the type account you wanted them to have. If you left that page blank, or enter your name in the wrong place, then XP logs you into an Admin. account.
