Shutting down an application that has frozen

• Normally you close a program by clicking on its Close icon, displayed at the top-right of a program window.  Sometimes a program will crash or freeze and you may not be able to close it down in the normal way.  In this case, if possible switch to any programs that are still responding and close them down (saving any data if necessary). 
  

• Click on the arrow to the right of the Start button, and from the popup menu displayed select the Shutdown command.
  
  
  

• If this does not work physically switch off your computer.  In the case of Desktop computers there is normally a power switch on the front or at the back of the computer.  When using a laptop computer you may have the hold down the on/off button for a short time in order to switch off the laptop.   Wait for at least 30 seconds and then switch the computer back on.  It may display a different opening screen than normal, in which case follow the on-screen instructions.
