Windows Photo Viewer

Windows Photo Viewer is an image viewer included in Windows 7 and later versions of Microsoft Windows.

It can show individual pictures, display all pictures in a folder as a slide show, reorient them in 90° increments, print them either directly or via an online print service, send them in e-mail or burn them to a disc. Windows Photo Viewer supports images in BMP, JPEG, JPEG XR, PNG, ICO, GIF and TIFF file formats.

In Windows 10 and later, Windows Photo Viewer was deprecated in favor of the Photos app. However, Windows Photo Viewer was not actually removed from the OS and it can be brought back with a registry tweak.
