You can configure the local security policy in Vista so the Windows Security dialog box will be displayed, requiring all users to press CTRL + ALT + DEL to log on. Users will be prompted to provide a valid username and password to access the computer.

You can configure this option by using the following steps:

  1. Click Start and click Control Panel.
  2. Click System and Maintenance, Administrative Tools and then the Local Security Policy.
  3. Within the console, expand Local Policies.
  4. Click Security Options. The various security options are displayed in the details pane.
  5. Scroll through the options and locate Interactive Logon: Do not require CTRL + ALT + DEL.
  6. Double click the security option.
  7. Select Disabled to require users to press CTRL + ALT + DEL.
  8. Click OK.
