View Admin At welcome Screen

By default windows XP doesn't show the Administrator in the user list at the welcome screen. Here's a way to get around it.

Now head up to HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Winlogon
\SpecialAccounts\Userlist.

Create a new DWORD entry and name it as Administrator and change its value to 1.Exit and Reboot for the changes to take effect.To change it back change its value to 0 or simply delete the key.
