In Windows 7 you have to enter a password in order to log in to Windows. This is to protect your PC from Unauthorized access by others. If you are only the one using your computer every time when you start Windows 7 need to to enter the password to log in. This becomes very irritating. So here is how to log in to Windows 7 without entering any user name or password .
In the run menu type control userpasswords2.
Just press WIN + R to get the RUN menu.
The user accounts windows will now open up.
Look for the option saying ” Users must enter a user name and password to use this computer ” and uncheck this option and press “OK”.
Now a windows opens up asking you to enter the current password you use to log in to Windows 7. Enter the password and confirm. Done!.
From now on when you boot to Windows you will not be asked or prompted to enter the user name and password. This can also save a couple of seconds while starting Windows.
