Fix Ctrl Alt Del not Working on Windows 10 / 11 (Solved)

CTRL+ALT+DEL is used to open the the Security options window. The options on the page allow users to change the password, log out, shut-down, or restart the system, and access the Task manager. All of these options are available on the system otherwise, but the purpose of the Security options window is to access these emergency options when the computer freezes and nothing else works.

If the Security options window ceases to work, it might not be an immediate emergency if the system is working fine, but needs to be resolved as soon as possible. In case we lose access to the security options window when needed, the only way to handle a frozen system would be to power it down, something that may damage the hardware or may result in loss of data.

  1. Another solution is flashing the bios with an upgraded version. Especially if you’ve been messing around with a certain battery white list on the bios itself. It caused ctrl alt and delete to stop working and the function and delete key turned on the laptop light, which its supposed to be the function key and the space bar key. flashed the bios again and it solved the issue.
