What key combination can you use to end a frozen program without losing unsaved work?

Utilizing Ctrl+Alt+Del is effective in managing unresponsive programs, as this key combination opens the Task Manager or a security options menu, enabling you to view running applications. When a program is frozen, you can select it within Task Manager and opt to "End Task." This action specifically targets the unresponsive application without directly shutting down the operating system, allowing you to potentially save other work that remains functional.

The other choices do not serve this purpose effectively. For instance, Ctrl+Z is primarily used for undoing actions within software applications, which would not help in dealing with a frozen program. Alt+F4 typically closes the currently active program, and if it is unresponsive, it may not allow you to save your work before closing. Shift+Esc is not a standard key combination associated with program management in most operating systems.

Therefore, using Ctrl+Alt+Del grants you a way to address the situation safely, allowing you to recover unsaved work in other applications while focusing on the one that has stopped responding.
