You can configure the local security policy so the Windows Security dialog box will be displayed, requiring all users to press CTRL + ALT + DEL to log on. Users will then be prompted to provide a valid username and password to access the computer.
You can configure this option in Windows Vista by using the following steps:
- Within the Control Panel, click System and Maintenance.
- Click Administrative Tools then the Local Security Policy.
- Within the console, expand Computer Configuration | Windows Settings | Security Settings | Local Policies.
- Click Security Options. The various security options are displayed in the details pane.
- Scroll through the options and locate Interactive Logon: Do not require CTRL + ALT + DEL.
- Double click the security option.
- Select Disabled to require users to press CTRL + ALT + DEL.
- Click OK.

For those who have problems trying to get Windows Vista (Ultimate) to require the user to press Ctrl+Alt+Del use the following:
I got the info from:

The post was by Nothize… He’s v.good as it works fine…. cheers mate.
Just to clarify:
Run Reg Edit - locate “HKEY_LOCAL_MACHINE” - “Software” - “Microsoft” - “Windows” - “CurrentVersion” - “Policies” - “System” - “dontdisplaylastusername” and change the value to “1″
Hope this saves you trawling the net like i had to

I have Vista Business on a Toshiba laptop. This particular security setting changes itself back to enable everytime I log off. So I get the ctrl alt del once but after that it’s gone. Is this some unique to Toshiba laptops? My computer at work, with same OS, does not have this problem.
