If you enable this policy setting, users are required to enter Windows credentials on the Secure Desktop by means of the trusted path mechanism. This means that before entering account and password information to authorize an elevation request, a user first need to press CTRL+ALT+DEL. This policy setting determines whether users must first press CTRL+ALT+DEL to establish a trusted path before typing account and password information to log on to computers in the environment. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Credential User Interface!Require trusted path for credential entry (2) REG: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\CredUI!EnableSecureCredentialPrompting
