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.
