The program you wish to be the default must be installed on your computer before you can set it as default.



Browsers, Preview, and other applications can be used to view a .pdf file.

When new applications are installed, you may be prompted on whether you would like to make it the default.



Windows 10

  1. Open Control Panel
  2. Change the View by: to  Category if needed
  3. Programs
  4. Default Programs
  5. Set your default programs
  6. Find the app type (Email, Maps, Music  Player, Photo Viewer, Video Player, or Web browser)
    • Tip: If what you want is not listed, you can also set defaults by file type, by protocol, or by app, using the links just below this section
  7. Click on the application icon that is currently set as default to bring up the Choose an app window
  8. From the Choose an app window, select the app you wish to be default from the list

  1. Search for and open Default Apps settings
  2. Scroll down to the bottom and click the link to Choose default apps by file type
