A. For security reasons it may be desirable to stop the last logon name logged on being display so to stop perform the following:
- Start the registry editor (Regedit.exe)
- Move to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
- Double click DontDisplayLastUserName
- Set to 1 and click OK
- Close the registry editor
This can also be done using the policy editor, and is under the Windows NT System - Logon tree, and tick "do not display last logged on username".
Under Windows 2000 dontdisplaylastusername has been moved to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system.
To assign using a Group Policy Object set under the Computer Configuration - Windows Settings - Security Settings - Local Policies - Security Options - Do not display last user name in logon screen
