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. 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
