To keep up the security, Users have to identify themselves during the Log-on process by
entering their username (and optional a password).
But if you are the only person having access and using the system (like at home) or if the system runs an automatic process without any user-control, you like the system to bootup (for example after a power-lost situation) without the requirement to press the Ctrl-Alt-DEL and entering your username, you like the boot process to continue immediately bringing up the desktop, starting up any program in the "Start-Up" program-folder ( as possible on Windows 95/98 and Windows NT4 with TweakUI (or a manual Registry setting).
 | Windows 2000 offers this functionality as part of the "Users and Password" applet in the Control-panel. |
 | By default, user are required to log on (the famous "ctrl-Alt-Del" during bootup), as defined by the checkmark. |
 | To bootup without Log-On screen, select first the default User Name and then take off the Checkmark. But this is NOT the "unsecure" Windows95/98, because even if you allow such a bootup without the identification of a user via the Logon-process, Windows 2000 ensures a minimum level of security: On selecting OK: |
 | You are prompted to define the default username (uses by default the select user of the previous window) and passsword to bypass the Logon- window. |
