How can I prevent users from using Ctrl+Alt+Del?
WinU can completely disable Ctrl+Alt+Del, or password-protect it. To set this up, go to the desk on which you want to add this protection. On the Input Control tab, check the box to disable Ctrl+Alt+Del. If you don’t give a password, when the user presses Ctrl+Alt+Del nothing will happen. If you do give a password, when the user presses Ctrl+Alt+Del the password box is displayed. If the user gives the Ctrl+Alt+Del password, the regular option appears (Task Manager, Close Programs box, or Windows options screen).
