hi, I don't know where my administrator a/c gone?. I install window xp proff. sp2 with default administrator user. Today I open user control panel and click on create new user. after entering a name it says u must select at least 1 a/c as administrator. I just click and then it open another desktop. But when i restart intermediate screen shows only one option, new user name which i created. what happen my old admin a/c and desktop. It is showing under c:\Documents and Settings\Administrator. But how to open this desktop now. 2ndly how to delete this newly created user. Under user control delete option is not available for this user which i set as administrator.
