I really messed my computer up.. I accidently disabled the start up file, I'm not sure of the technical name.  When I start my computer, it says to click on user, there is no user.  How do I go in and enable the program?
I know what I did was dumb, I should have read more carefully, I was trying to disable the password, not the prigram.you deleted your LOG on?What version of Windows (95, 98, ME, 2k, XP)?not deleted, disabled.  I went into security and disabled it, than restarted my computer.windows xp.  we tried reinstalling windows, didn't work.At log on screen, try Ctrl-Alt-Del, 2 times.  That should let you log on as Administrator.  Then create a new account and log off.  Then log on as new user.when i do that it asks for a password, when i ENTER that it says to make sure that my domain and user name is correct.  user name is administrator.  I have the right password, that is what got me into trouble in the first place.User names and passwords are case sensitive.I know that, but the password I know is correct, but I am not sure about the domain.Domain is "Workgroup"Okay, now it says my account has been disabled, please see your SYSTEM admin  Are you saying:  both User and administrator accounts (profiles), have been disabled?the domain was administrator, i typed the password incorectly the first time, now its giving me the message i wrote above. the admin was the only one availabe the guest one has been disabled.  im not sure about  a user,  if i have one there was NEVER a password set.its asking for a user name and password.  it automaticaly is showing admin, i put in the password, than it shows the message.  we DONT have passwords for anything else, that i know of.  this really stinks, i was just trying to put a password on a personal file, n ot the whole computer.
