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. Fix: (1) GPO: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options!Interactive logon: Do not require CTRL+ALT+DEL (2) REG: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System!DisableCAD
