By default, Windows NT 4.0 displays the name of the last person who logged on the system. This can pose a security threat, especially if a user's password can be guessed from the account name or the login environment. To turn this "feature" off take the following steps:
Launch the Registry editor. (regedt32)
Go to Hkey_Local_Machine key.
Locate the Subkey\Software\Microsoft\WindowsNT\CurrentVersion\Winlogon.
Select the ReportBootOK item.
Select Edit/New/String Value from the menu bar.
Type DontDisplayLastUserName for the string's name.
Double-click the new string to edit its value.
Change the value to 1.
Click OK.
Close the Registry editor.
