Disable the Turn off computer button on the Welcome screen

By default, the Microsoft Windows XP logon screen displays a Turn off computer button. This display seems convenient, until one of your kids happens to shut down your computer and close all your programs. To prevent this from happening, you can disable the Turn off computer button. You can still shut down your computer; you just have to log on with a computer administrator account first.

Useless. I agree, the button on the log in screen is gone, but when I press the power button, a dialog asking to shut down or stand by still appears, and works.

How do I get rid of any possibility to have unauthorized users shut down my computer while my screen is locked??

I could just disable the power button altogether by assigning it to "Do nothing", but I still want the power button to function when I'm logged in and not locked.
