You can try the suggested procedure from the following MSKB article:
Q281140 -" HOW TO: Disable the Local Administrator Account in Windows"
You should use the culprit account instead of Administrator account (as presented in this article).

A rather interesting problem has come about on my computer. I found a new Administrator account on my system. The system is running XP Pro in my law office on a box with 256 megs of RAM and beau coup hard drive space. It's a 2+ gHz processor (Intel).
Normally, you would say, "Simply delete the account." Nope. You CANNOT delete this account. Why, you ask? Because whoever/whatever put this account on my system was too aware of that. There is no delete capabilty. Yes, I know how to delete user accounts, but there is nothing shown, except Change Password and change the picture.
I have put in a unique password that will never be figured out without a ton of work. But my question, and I have asked this in several such forums but never seem to get a good answer, is how do I REMOVE the darn account? If I cannot do it the regular way (but thy are somehow not shown), then can I delete it some other way, using regedit or whatever?
Would reinstalling XP Pro work?
I believe that this thing came via the Internet. There is no one smart enough on the cleaning crew to do this. None of my clients are computer literate enough. I think it was downloaded and activated inadvertently by a former secretary (that is why she is "former") who downloaded music off my the Internet by using my computer when I was out of the office. The name on the user account is King, if that helps.
