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 10/11.

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 11 and earlier OS.

photoviewer.dll file information
Windows Photo Viewer – photoviewer.dll in Windows 10 version 21H1.

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 and 11.
