Solve : Can't log into Windows 7 at the welcome screen!?

1.	Solve : Can't log into Windows 7 at the welcome screen!?
Answer» I was enabling AUTOMATIC logon on Windows 7 by control userpasswords2. So I unchecked the Users must enter a user NAME and password to use this computer box. Then it asked me for the user account password, and I mistakenly entered a password thinking it NEEDED one. Even though I had no password set up for my own personal account. So now the problem is that I can't sign into Windows. At the welcome screen it says "The username or password is incorrect". And it doesn't let me CREATE a RESET disk. The error message is displayed even before I can type anything in the logon screen. Please help!!!! Thanksss!
