Press the "Windows Key+R" to bring up the Run line. Type: control userpasswords2 , then press the "Enter" key. When the "User Accounts" window loads, UNCHECK the box that says "Users must use a username and password to use this computer", then click on "Apply", then OK. After that, you'll probably be asked to confirm the automatic sign-in option and you'll need to type in your password TWICE, then reboot the computer.

Hope this helps.
