Interactive logon: Do not require CTRL+ALT+DEL  This security setting determines whether pressing CTRL+ALT+DEL is required before a user can log on.  If this policy is enabled on a computer, a user is not required to press CTRL+ALT+DEL to log on. Not having to press CTRL+ALT+DEL leaves users susceptible to attacks that attempt to intercept the users' passwords. Requiring CTRL+ALT+DEL before users log on ensures that users are communicating by means of a trusted path when entering their passwords.  If this policy is disabled, any user is required to press CTRL+ALT+DEL before logging on to Windows (unless they are using a smart card for Windows logon).  Default on domain-computers: Disabled. Default on stand-alone computers: Enabled.
