Disable: 'Interactive logon: Do not require CTRL+ALT+DEL' This policy setting determines whether users must press CTRL+ALT+DEL before they log on. If you enable this policy setting, users can log on without this key combination. If you disable this policy setting, users must press CTRL+ALT+DEL before they log on to Windows unless they use a smart card for Windows logon. A smart card is a tamper-proof device that stores security information. Counter Measure: Configure the Disable CTRL+ALT+DEL requirement for logon setting to Disabled. Potential Impact: Unless they use a smart card to log on, users will have to simultaneously press three keys before the logon dialog box will display.
