|If you are referring to being able to just bypass the user log-in page then you must only have one user enabled. If there are two or more then you must have the log in to pick the user that is booting up!|
You can disable the guest log-on and also the ASPnet as well or remove it completely. You cannot remove the guest account..just disable it. Then when boot the system will start to your desktop.
Control panel >users accounts and change each user account from the admin capable account!
Change Is Good
