This article describes how to prevent the name of the last logged-on user /domain from being displayed in the Log On to Windows dialog box. By default, Windows displays the name of the last user who successfully logged on to the computer. This name is displayed in the Log On to Windows dialog box. Security administrators may prefer that the last logged-on user name not be displayed in the Log On to Windows dialog box.
To hide these details (KB324740): Go to the following location: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options. Now apply the third option, you are not displaying DOMAIN\Username details when the machine is locked (see below).
This setting has three options when you enable it: 1) User display name, domain and user names (Value = 0x1), 2)
User display name only (Value = 0x2), 3) Do not display user information (Value =0x3)
