Windows Photo Viewer is one of the things that gets removed, or hidden from access after installing Windows 10. The new Photos app takes charge as the default handler for image files in Windows 10.
Good news is that the Windows Photo Viewer application still exists in the same location in Windows 10, but what’s removed is only its registration. If you’re not a fan of the new Photos app, you can revert back to Windows Photo Viewer which itself is a sleek application.
Windows 10 has an updated version of the DLL, but for some reason Microsoft decided to keep this application hidden from users.

Restoring Windows Photo Viewer in Windows 10
Download w10-wpv-restore.zip, unzip and double-click the attached REG file. This registers Windows Photo Viewer with Default Programs, and adds file association settings for BMP, DIB, JFIF, JPE, JPEG, JPG, PNG, TIF, TIFF, WDP types.
Cannot import the REG file?
If you get this error when running the REG file, no problem. Most of the settings would have been written correctly. Perhaps the file got stuck when writing to TIF/TIFF association settings, as the association for TIF/TIFF already exists even after upgrading to Windows 10. You may ignore the error message and move on.
Click Start, Control Panel, Default Programs. Click Set your default programs, and select Windows Photo Viewer from the list.
