HELP: Deleting User Accounts

Okay, this is really annoying me...

This PC was bought few months ago, Windows XP SP1, it had no User Accounts, so we just use the default Admin Account all the time and install programs & stuff. And yesterday, my lil geek wannabe sister created the 1st user account, then it started to login to useless_account every time we boost up the PC. What I want is, log on Normal Mode as Default Admin Account and get useless_account deleted. Do you know what I mean? Okay, all my programs and stuff are all in the default admin account, then my sister made an user account, it's the first , then it goes onto useless_account instead of the default admin account everytime I turn on the PC. I tried login as admin using debug mode, but it won't let me delete useless_account when I got there. I do not want any accounts, I want to get back to normal account we used to and delete the useless_account. Well, the one we used before is not an account, it's just the default settings, omg, I don't know how to express it in English...

Experts post ONLY.

 

EDIT:

oh sorry I thought that you had an account and so did your sister x.x
also forgive me if i'm wrong but i'm pretty sure the default admin account can't be deleted =/ my post was based on the presumption that there were 2 admin accounts floating around. anyways, read my post and see if it helps

only thing I can suggest is that u tell your parents and say that you can't do your work unless you have admin to install a program (photoshop, for example), and once she logs in for you, do what I said below but instead of using delete use the "set password" command to reset the password. Once you have the account back I suggest u create another account with admin privileges just in case this happens again..hopefully your sister doesn't know how to delete accounts.

presuming you have admin...

ctrl+R->gets you into the run command
type in "mmc"->takes u to the microsoft management console
once in the console, press ctrl+M to add a snap in
press "Add" button, and navigate to "Local users and groups"
Select local computer, press finish in the new dialog box, close in the add standalone snap-in and press OK
expand local users and groups by pressing the + on the left hand side window
navigate to users
right click the account she created, press delete, confirm and voila.

 

Kk, let's get straight to the point. This PC is purchased few months ago, and it had no user accounts at all. I just use the regular default admin account everytime. Til today, my geek wannabe sister created a new user account, then my PC started to log on 'useless_account' instead of the regular one we normally use when I start it up. The 'useless_account' is the 1st user account made in this PC, I want to get rid of it. I do not want any user accounts in this pc. How can I delete 'useless_account' and make my PC login its default admin account? I went into Debug Mode as Administrator and tried deleting the 'useless_account', but it doesn't let me to, I even tried ' Net User useless_account \delete ', it said no such account name. All I wanted is delete that only one user account and go back to the default account, because all my stuff are in it, I can't be stuffed to reinstalling everything in a new user account, so please help me, hope you could understand what I'm saying...

Please...

Aussie Boy, maybe you don't get me, or the other way around, I don't know, but

This 'useless_account' is THE FIRST & THE ONLY account ever made in my PC, and all my programs and stuff are installed in the regular default admin account (which is no password needed), so I wanna remove 'useless_account' and get back to the previous one I used.

 

Solution found, thank god.
