When you start Windows 7 or Windows 8, you are asked to enter your password to be able to log in. This is to protect your Windows PC from unauthorized access. But if you are the only person to use the PC and if you do not wish to be asked for the password every time, you may get rid of this process and log on directly and automatically into Windows, without entering a password.
Login automatically in Windows
To turn off Windows login screen & log on automatically to Windows, do the following
Type control userpasswords2 in start search and hit Enter to bring up the User Accounts window.
Alternatively, press Win+R to bring up the Run box. Next type control userpasswords2 and click OK.
Uncheck Users must enter a user name and password to use this computer and click Apply > OK.
Restart your computer.
Once you have done this you will find that you will be able to log on automatically to your Windows computer, without seeing the login screen and having to enter your password or credentials.
