Control-Alt-Delete - Enable/Disable
To Enable or Disable the CTRL+ALT+DELETE Sequence
1. Click Start, click Control Panel, and then click User Accounts.
2. Click the Advanced tab.
3. In the "Secure logon" section, select or clear the "Require users to press Ctrl+Alt+Delete" check box.
If you want to set up a requirement for a user to press CTRL+ALT+DEL before the classic logon is displayed, in the same manner as it behaves on Windows XP Server:
1. Click Start/Run/Regedit, and then click OK.
2. Select the Winlogon subkey at the following registry location:
HKEY_LOCAL_MACHINE\Softwar
3. Click Edit, click New, and then click "DWORD value".
4. Change the value name to "DisableCAD" (without the quotes) and press ENTER.
5. Keep the data value set to 0 which is displayed as 0x00000000(0).
If the Welcome screen is enabled, the computer can be locked if you press CTRL+ALT+DELETE (to open Task Manager), and then click Lock Computer or click Switch User on the Shut Down menu.
Control, Alt, Delete Process Explained and Key Commands
Control-Alt-Delete - Use Crtl + Alt + Delete to Restart the Computer
Normally when you press Ctrl + Alt + Delete the Windows task list is displayed. Using this tweak the key combination will instead reboot the computer. Open the SYSTEM.INI file found in the Windows directory using Notepad.
Under the [386Enh] section create or modify the value named "KybdReboot". Set the value to equal "True" to cause the system to reboot on the key combination or "False" to show the task list. For example:
[386Enh]
KybdReboot=False
Restart Windows for the change to take effect.

Hi contactabbas,
The Ctrl+Alt+Del functionality is embedded in the msgina.dll. To change that behavior you have to replace msgina.dll with your own. Check this white paper from M$:
