(TIP: To take Windows XP registry editor- Start > Run Type there regedit.exe And press enter)



If you’ve elected to use the standard logon dialog box instead of the Welcome screen, or if the XP computer is joined to a domain, XP tries to be helpful by displaying the account name of the last user who logged onto the computer; you only have to type in the password. However, this is a security issue because it gives a hacker half of the information needed to log on. Why make it easier? Of course, you should already have renamed the administrator account and disabled the guest account so a hacker won’t have those account names to use. The next step is to disable the display of the last logged-on user. Here’s how:


1. In your registry editor, navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Policies\System.
2. In an empty portion of the right details pane, right-click and select New | DWORD Value.
3. Rename the new value dontdisplaylastusername.
4. Double-click the new value and enter 1 in the Value Data field.



Have a nice hack.
