Using Windows Photo Viewer as default image viewer on Windows 10

Out of the box Windows 10 has Trusted Windows Store apps as default programs for numerous file extensions including most popular image formats (jpg, png, bmp, gif, ico, etc.). Via the "Default Programs" functionality in Control Panel you may not even be able to change the default program for some file formats as in the case of the Windows Photo Viewer (which I personally prefer over the Photos Windows Store app for viewing images) because it does not even have the requested file extensions associated to it (Windows Photo Viewer is associated to .tif and .tiff files only). If you'd like to use Windows Photo Viewer for viewing other supported image files you can do as it is described in this article.
