To select an application or other window in Windows 7 you must click on the window with the mouse. However, in some computing environments you can select windows just by hovering over them with the mouse pointer. If you find this convenient you can enable this in Windows 7 by doing the following:
1. Click the "Start" menu, choosing "All Programs", "Accessories", "Ease of Access", "Ease of Access Center".
2. When the "Ease of Access Center" window appears, scroll down and click on "Make the mouse easier to use".
3. On the following screen, underneath "Make it easier to manage windows", check "Activate a window by hovering over it with the mouse".
