Don't know how to close (quit) programs/applications (Unresponsive program/application)

If a program became unresponsive and you weren't able to quit it via any other method, shut it down. This method is more helpful to laptop users than to desktop computer users, because desktop computers have a dedicated restart button.

To force-shut-down the computer, press and hold the Power On/Off button until the cooling fans stop working (which should be in around 15-20 seconds after you have pressed the power button). Turn it back on after a minute or two.

Pulling out the battery when the mobile device is on is one of the best and easiest ways to close the applications that have become unresponsive.

If your device's battery is removable, remove it while your device is on and reinsert it after 20-30 seconds.

Note: No data will be lost during this process. If your device's battery is not removable, check out the other solutions on how to restart your device.

1. Press Ctrl + Shift + Esc
   
   

   
   
   

2.  Select the program you wish to close (usually the one whose Status is Not Responding) -> Click End Task
   
   

   
   
   

3. Click the X icon in the top-right corner to close the Task Manager

If the above-mentioned method didn't work:

1. 1. Right-click the program and select Go to Process -> Click End Process (or End Task on Windows 8/8.1 or Windows 10) -> Click End Process again to confirm
      
      

      

Note: The procedure is the same if you use Windows 8(.1) or 10, only the user interface of the Task Manager is different.

If a program became unresponsive and you are unable to close via the Task Manager, a simple restart (by pressing the restart button on the computer case) of the computer will do the trick.

If you use a laptop (which doesn't have a restart button), check out the don't know how to restart my device solutions.

If an application became unresponsive and you cannot close it, and you have access to the Settings, you can force-stop it.
