Early Windows versions like Windows XP or Windows 2000 came with the classic logon dialog, for which the user could turn on the requirement to press CTRL + ALT + DEL shortcut keys together before logging on. In modern versions of Windows, the classic logon dialog was removed, however, it is still possible to enable the CTRL + ALT + DEL requirement. If you turn this on, you must press these keys before you sign in or unlock your PC. Follow these simple instructions to turn on this feature.
To enable the secure logon prompt with Ctrl+Alt+Delete, you need to do the following steps.
- Open Registry Editor
- Go to the following key:
- Create or modify the DisableCAD DWORD parameter. Set it to 0 to enable secure logon prompt with Ctrl+Alt+Delete. Set it to 1 to disable it and restore defaults.
Alternatively, you can do the the same using the control userpasswords2 command.
