When Windows freezes, Task Manager is your rescue tool.

Steps:

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Go to Processes tab and find the app marked “Not Responding.”
3. Right-click → End Task.
4. If the entire system is frozen, press Ctrl + Alt + Delete → Task Manager → End the problem app.

💡 Pro tip: Avoid ending processes like “Windows Explorer” or “System” — these are essential for Windows to run.
