Not all apps on your Windows 8 computer will run from the desktop screen although some people may wish that they would!  From time-to-time, you may need to make changes to the settings in your apps to customize your preferences or just make other changes that may be required for your app.  You can get started by following these steps:

  1. With your app open, click the Settings charm.
  2. Select the settings that you would like to change within your app customized to your preferences.
