This policy setting determines whether the account name of the last user to log on to the client computers in your organization will be displayed in each computer's respective Windows logon screen. Enable this policy setting to prevent intruders from collecting account names visually from the screens of desktop or laptop computers in your organization. Countermeasure: Configure the "Interactive logon: Display user information when the session is locked" setting to "Do not display user information." The possible values for this policy setting are: * User display name, domain, and user names. * User display name only. * Do not display user information. Potential Impact: Users will not see their user name or domain name when unlocking their computer, they will have to enter that information.
