Maximizing

• The easiest way to take care of multiple windows on your screen is to look at your task bar --- the long bar at the bottom of the screen with the "Start" button on it. You can click on each individual window to maximize them, then you can close each.
  
  

Task Bar

• Instead of going through the trouble of maximizing each window, you can right-click the task bar on the window you want to close. This will bring up a menu where you can select "close."
  
  

Task Manager

• This is an advanced technique and should only be used if necessary. Hold "CTRL" and "ALT" on the keyboard, then quickly press "DEL" and release all three at the same time. This will bring up the Task Manager. In the "Applications" screen, highlight each window and choose "end task."
