Ctrl+Alt+Del is a popular key sequence on which we all depend to escape a problem or exit a function or simply get away with boring programs. Ctrl+Alt+Del is the keyboard sequence that sends a command to the CPU when this key is pressed to open a window with a menu to access tasks such as logging out, locking the system, changing users, opening a task manager, or even shutting down the system. That is, whenever your system crashes or is destroyed by some other cause, you must give it the three-finger greeting, Ctrl+Alt+Del, to reboot the entire system.

Ctrl+Alt+Del does not work

In scenarios where programs crash, Windows users simply open the Task Manager by pressing Ctrl+Alt+Del. In the Task Manager, users can repair, make changes, test, complete the process and restart the program. But sometimes the Ctrl+Alt+Del keys may not work on your system. This problem usually occurs if you have updated the system with unofficial firmware or if you have installed third-party applications. What really happens when you install a third-party application is that it makes changes to the registry and changes the default values. In this case, it is necessary to identify and uninstall the problematic application.

In this article, we discuss some solutions to solve this problem. But before trying our solution, physically clean the keyboard keys and check if you have not missed Windows updates, as installing the latest updates may solve the problem.
