Closing an application that is not responding

• Occasionally when you are running Windows Vista, you may find that you are unable to close an application that has ‘crashed’.  If this happens, you need to press the Ctrl+Alt+Del keys simultaneously.  A list of options will be displayed.  Select the Start Task Manager option. This will display the Task Manager dialog box. 
  
  
  

• In the example illustrated, all the programs are running normally.  If a program was no longer responding you would see a message in the Status column such as Not Responding.  In this case you would select the non-responding application from the list displayed and then click on the End Task button.
  
  TIP: It is a good idea to completely close down Windows and then restart Windows after a program has crashed.
