Ctrl + Alt + Del (PC)
The ‘Ctrl + Alt + Del’ keyboard shortcut is a critical command for Windows users, traditionally used to access the system’s security options, including the Task Manager, Sign out, and Lock functions. Originally designed to reboot the computer, its function has evolved to provide a secure gateway to various system-related tasks. Invoking this command can be particularly useful in situations where an application freezes, as it allows the user to access the Task Manager to forcibly close the unresponsive program. Additionally, it serves as a security measure, enabling users to lock their workstation or change their password. Despite its power, it should be used judiciously, as unsaved work may be lost when terminating applications.
