Control + Alt + Delete: What is your key combination and what is it for?

The key combination Control + Alt + Delete is also known as Ctrl + Alt + Del (Delete). This sequence of keys is a keyboard command, used to make shortcuts on the pc ; that is, when we press these three keys, we tell the software or operating system that it must perform a certain task, such as logging in or interrupting a function.

The creator of this script is Microsoft mogul Bill Gates ; who recently assured that it was a mistake to create this shortcut using the combination of three keys, since both hands must be used to carry out that command.

Bill Gates believes that this shortcut could have been created by pressing a single key, however, this combination of letters is a function widely used by Windows users.

What is this command for?

This key combination can be used in various procedures running on the pc; but you must bear in mind that for the function to be carried out you have to press the three keys simultaneously (Ctrl + Alt + Del).

  3.  This command is very useful for closing unresponsive programs or when Windows freezes.
  4. It is used to put the equipment to sleep (be careful, suspend is different from hibernate ).

These key combinations are applicable to perform functions on computers with Windows operating system, if you have a MacOS computer, the above-mentioned functions are not performed with the Ctrl + Alt + Del keys; since, you must use other keys to carry out those functions.
