This is what I wanna do below: Only problem is that I don't have an Advanced tab on the User Account window (I'm using an account that has admin privileges). I have set the login so that you can't Fast Switch and turned off the Welcome screen.
I'm using XP Prof and not on a domain, just use a simple Peer2Peer network at home. And the Help feature won't work either.
Salute before you log on
Setting your PC so that it requires you to press Ctrl-Alt-Delete before you log on to Windows protects your computer from Trojan horse programs, which can imitate log-on screens and trick you into revealing your user name and password. Using the "three-finger salute" ensures that you see the authentic Windows log-on screen. To enable this setting for a computer connected to a network domain, log on as the administrator, open the User Accounts Control Panel as described above, and click the Advanced tab. Under Secure Logon, check the option Require users to press Ctrl+Alt+Delete. Then click OK.
If your PC is not connected to a network domain, log on as an administrator and open User Accounts. Click Change the way users log on or off. Uncheck Use the Welcome screen and click Apply Options. Users will now have to type both their account name and their password after pressing Ctrl-Alt-Delete. They also lose the ability to do fast user switching, but the PC will be a bit more secure.Use the keyboard to lock your system. Going for a cup of coffee? Lunch? A meeting? Play it safe and lock your PC so that you have to enter a password to use it again. If your system is connected to a domain, simply press Ctrl-Alt-Delete and click Lock Computer. You'll have to press Ctrl-Alt-Delete again and enter your password when you return. If you're not on a domain, press Windows-L to bring up the log-on screen without closing any apps. When you come back, pick your account and enter the password.
