I have just installed Windows XP + SP2 on my newly formatted hard drive. I created just the one user (myself) for the computer. My system works OK, but when I tried to open User Accounts, it returns the message "The current user account is not recognised restart the computer and then open User Accounts". After restarting the computer and logging on as myself, if I restart User Accounts, then I get the same message again. In addition, I cannot log on as Administrator, since it needs a password, howver I have not set any passwords. I have tried to do a Windows repair, but this has had no effect whatsoever.
