4 Ways To Enable Secure Logon (Ctrl + Alt + Del) In Windows 8

Ctrl + Alt + Delete (Also known as three finger salute or secure attention) is a keyboard command which is invoked by pressing Ctrl, Alt and Del keys simultaneously. It was first used by David Bradley, a designer of the original IBM PC, who used it for soft-rebooting the Operating System.

Those who remember Windows 98 or earlier Operating Systems, those systems could be restarted using this sequence multiple times. But after Windows NT, this sequence is used for secure logon. If you are using a shared computer, you must enable the secure logon feature to make sure you are safe from any threats and misunderstandings. You can read more about secure logon in this Wikipedia article.

Using User Accounts interface

The easiest way to enable secure logon feature in Windows 8 is by enabling it visually. Just follow the steps below to enable Ctrl + Alt + Del sequence on logon in Windows 8.

  1. Go to Run –> control userpasswords2
  2. Go to the Advanced tab
  3. Check “Require users to press Ctrl + Alt + Delete” option under Secure sign-in

This will enable the secure logon immediately and will be visible the next time you login. Windows 8 shows a message on logon to press the Ctrl + Alt + Delete keys in order to continue.

An interesting thing to note here is the note that Microsoft has made making it easier for us to understand why this secure sequence should be enabled.

For added security, you can require users to press Ctrl + Alt + Delete before signing in. This guarantees that the authentic Windows sign-in screen appears, protecting the system from programs that mimic a sign-in to retrieve password info.
