Anyone who works frequently with images in Windows will appreciate the convenience of being able to preview an image quickly without opening a full editor. Windows 7 and 8 had the built-in Photo Viewer, which allowed you to preview images in File Explorer. Windows 10's Photo Viewer is still available, but it can no longer be used to preview files in File Explorer. What can you do to fix this? A registry tweak online can be used to create an Image Preview command within Windows 10 File Explorer. Simply right-click the image that you want to view and choose Image Preview. You can now view the entire image, zoom in or out, and switch between images with Photo Viewer. Office.com/setup
