Coming to Windows 10, Microsoft universally replaced it with its updated version Photos. Formerly, it was known as Windows Picture and Fax Viewer and later renamed to Windows Photo Viewer. Windows Photo Viewer has been a part of the Windows family since Windows XP.
Now you can select any Photo viewer as your default image viewer. To do that on Windows 10, head over to the search bar and type Default. Next, go to Default Apps Settings > Photos. You also have to make it your default Photo viewer app. Just a heads up, installing a third-party photo viewer app isn’t going to be enough.
