When the application freezes, you can force shut down through system tools and troubleshoot the cause. 1. Use Task Manager (Windows) or Activity Monitor (Mac) to find the frozen program and end the task; 2. Try to close the application using keyboard shortcuts such as Alt F4 (Windows) or Command Q (Mac); 3. Before restarting the application, you can clear its cached data to fix the failure. The paths are Windows C:\Users\YourName\AppData\Local and Mac ~/Library/Application Support/; 4. Check for resource occupation or software conflicts, and close unnecessary background programs or extensions to prevent freezing.

How to fix an application that has frozen without restarting the computer

When an application freezes, it can be frustrating—especially if you don't want to restart your whole computer. The good news is, there are several ways to unfreeze or close a frozen app without rebooting.

How to fix an application that has frozen without restarting the computer

1. Use Task Manager (Windows) or Activity Monitor (Mac)

If an app becomes unresponsive, the first place to go is your system's built-in task manager.

How to fix an application that has frozen without restarting the computer

On Windows:

  • Press Ctrl Shift Esc to open Task Manager directly.
  • Find the frozen application under the "Processes" tab.
  • Right-click it and choose End Task .

On Mac:

  • Press Command Space to open Spotlight, type Activity Monitor , and hit Enter.
  • Locate the frozen app in the list.
  • Click the X button in the top-left corner of the window and confirm with Force Quit .

This usually stops the app cleanly without affecting other programs or requiring a full reboot.

2. Try Keyboard Shortcuts to Close the App

Sometimes you can force-close an app using just your keyboard.

  • On Windows: Alt F4 will try to close the active window. If that doesn't work, combine it with Task Manager as above.
  • On Mac: Command Q quits the active app. If it's frozen, this might not work—but it's worth trying before diving into Activity Monitor.

These shortcuts are especially handy when the mouse isn't responding well or the interface is completely locked up.

3. Restart the Application or Clear Its Cache

After closing the frozen app, you may want to reopen it. But if it keeps freezing, consider clearing its cache or temporary files.

  • Look for app-specific settings or preferences folders:
    • On Windows: Usually found in C:\Users\YourName\AppData\Local .
    • On Mac: Go to ~/Library/Application Support/ .

Deleting cached data can resolve glitches that cause freezing. Just make sure not to delete anything labeled as important or related to saved progress.

4. Check for Conflicts or Resource Overload

Sometimes apps freeze because they're fighting for memory or CPU power.

  • Open Task Manager (Windows) or Activity Monitor (Mac) again and check if other apps are using excessive resources.
  • Temporarily close background apps that aren't essential.
  • Also, check if any recent software updates or new extensions could be causing the issue.

For example, a browser with too many tabs open can sometimes make one tab freeze without affecting the whole system. Closing some tabs might help without needing to restart everything.


That's basically how you deal with a frozen app without restarting your computer. It's usually a matter of closing the program safely through system tools, then checking what might have caused the problem. Not too complicated, but easy to forget when you're in the middle of something important.
