How to start Windows without username password authentication

Sometimes it is quite annoying typing the same username and password to login to Windows again and again. And if you have OEM  installed Windows then they have their own username password already configured for your laptop/desktop.

Procedure is very simple  –

• Open Run Dialog Box from Start Menu and type control userpasswords2.
• Uncheck the box which says  "Users must enter a user name and password to use this computer"
• Press OK button and then verify your username and password once to apply the settings.

So from next time you won’t be prompted to enter your username/password again. Also, do remember, follow the same trick to make Windows accessible by username password authentication.
