How to enable CTRL + ALT + DEL logon requirement in Windows 10

If you are familiar with early Windows versions like Windows XP or Windows 2000, you might remember their classic logon dialog. It came with user name and password fields. As an additional protection, those operating systems had the ability to turn on the CTRL + ALT + DEL requirement before signing in to your user account. In Windows 10, the login screen is again completely reworked by Microsoft, however, it is still possible to turn on the Ctrl + Alt + Del requirement. Here is how it can be done.
