Skip welcome screen
You can choose to log into Windows automatically and bypass the welcome screen by making a simple tweak. To do this, choose 'Start | Run' and enter control userpasswords2 into the 'Open' bar. Click 'OK' to see a dialog showing each user installed on the PC.
Clear the box marked 'Users must enter a user name and password to use this computer'. Click 'OK'. Now restart your PC and you should go directly to your desktop.
