If you are using your notebook in public places and you leave it unattended is a good idea that you have a login screen requesting password to access the pc. At home on your desktop or on that laptop only you are using is nice to be able to push the power button go get your coffee and come back at a fully loaded windows ready to open you favorite news site . Here is how to disable the login screen in Windows 8.1
Click Run and write netplwiz press OK
Highlight your account and uncheck “Users must enter a user name and password to use this computer.”
Click apply. You will have to reboot for this to take effect.
To go directly to desktop right click your taskbar , click properties , go to Navigation tab and check “When I sign in or close all apps on a screen, go to the desktop instead of start”
Click apply and you are set .
