Windows Photo Viewer is one of the things that gets removed or hidden from access after upgrading to Windows 10. The new Photos app takes charge as the default handler for image files in Windows 10. The good news is Windows Photo Viewer application still exists in the same location in Windows 10, but what is removed is only its registration.
Windows Photo Viewer is a lightweight app similar to the Office Picture Manager and Windows Live Photo Gallery, both of which are discontinued by Microsoft. But, Windows Photo Viewer remains an integral part of Windows 10.
Windows Photo Viewer is powered by a single DLL file named
photoviewer.dll located in the
C:\Program Files\Windows Photo Viewer directory in Windows 10 and earlier OS.
For example, this command-line will open a file named
D:\sample.png using Windows Photo Viewer:
rundll32.exe "%ProgramFiles%\Windows Photo Viewer\PhotoViewer.dll", ImageView_Fullscreen d:\sample.png
Now, all we need to do is add Windows Photo Viewer file association settings to the registry. If you’re not a fan of the new Photos app, you can restore the missing Windows Photo Viewer registration in Windows 10.
