Windows 10 comes with its new Photos app and replaces Windows Photo Viewer to display Photos. But I think personally, Windows Photo Viewer is very light and does not take up a lot of resources compared to modern Photos. Well for that for you who want to Enable Photo Viewer in Windows 10, follow steps below.
- Open settings.
- Click Apps.
- Click Default apps > Photo viewer > Windows Photo Viewer.
- Now you can setting Windows Photo Viewer as default photo viewer.
