When he starts Windows XP and the system has more users (Users Account), by default, a graphic screen with the names and their icons will appear. In this "Welcome Screen"The user has the option to choose the user from which he wants to run.

As a rule, this option is activated when there are two or more users on a system, idifier whether or not they are protected by a password. When there is only one user on a PC and it is not protected with a password, this Welcome / Login Screen can become stressful. Oblige the user as after starting PCto click on the user's icon to run the system.

When you restart the operating system, you will see that it disappears Welcome Screen. This option is indicated for the systems that are a single user account on the operating system. Administrator. Ahh. In order to change this option (valid on the PCs that have more users), you must be logged in a user with administrator privileges.
