Microsoft Windows XP Inside Out, Second Edition In any case, if you want to prevent others from using your account, you must protect your account with a password. When you choose any of these options, Windows hides whatever you were working on. Your computer continues to run (subject to power management settings), and any resources shared by your computer remain available to other users on the network.

Ordinarily, the Administrator account is hidden from view. It appears on the Welcome screen only in the following situations:

No other administrative user accounts exist. You start your computer in Safe Mode (by pressing F8 during startup). The Administrator account is logged on and you re using Fast User Switching.

Nonetheless, the account does exist, and it takes care of some important functions. First, because it can t be deleted, it provides a safety net in case you somehow manage to delete all other accounts. You can log on as Administrator and then create other accounts. Second, it s the only account that can log on to the Recovery Console, your last-ditch opportunity for repairing a damaged system. Note

By default, the Administrator password in Windows XP Home Edition is blank. This isn t the gaping security hole that you might imagine, however, because in Home Edition the Administrator account is barred from logging on locally or through a network connection. You do, however, need to know that the password is blank if you ever need to run Recovery Console, which requires the Administrator password. If the blank password concerns you, you can change it. For details, see Securing the Administrator Account.

If you re using Windows XP Professional, you can log on as Administrator. If the Welcome screen is enabled, press Ctrl+Alt+Delete twice at the Welcome screen to display the Log On To Windows dialog box. (Be sure that no other account is logged on when you do this.) If the Welcome screen is disabled, press Ctrl+Alt+Delete one time as you would to log on with any other account. Type Administrator in the User Name box, and enter the password you created for the Administrator account during setup. Note Except in Safe Mode, Windows XP Home Edition users can t log on using the Administrator account, because it is prevented by account restrictions from logging on. To log on to the Administrator account using Windows XP Home Edition, first make sure that your system is not set up to bypass the logon screen. (See Bypassing the Logon Screen, page 223.) Then press F8 while booting and choose Safe Mode from the menu that appears.

Add Administrator to the Welcome screen If you re using Windows XP Professional, you can add Administrator to the Welcome screen, without eliminating all other administrative accounts, by modifying the registry. Use Registry Editor to navigate to HKLM\Software\Microsoft\WindowsNT\ CurrentVersion\Winlogon\ SpecialAccounts\UserList. In this subkey, create the new DWORD value Administrator. Then set this value to 1. To remove Administrator from the Welcome screen, return to the registry and set the Administrator value to 0.

Because an account named Administrator exists on almost every computer running Windows XP, and because this account is all-powerful, malevolent hackers might attempt to break into a computer using the Administrator account. After all, they already know the user name, so they just need to figure out the password. You can make your Administrator account more secure in two ways:
