    All image files are of type "unhandled extension handler finder"


    Help! All of my image files are listed as File Type "Unhandled Extension Handler Finder!"

    They are all doing this, but let's use the most important file type for me, JPG, as an example. The default program is set to "Photos," and, when I double click on a JPG file, it opens in Photos, exactly as it should. But in the file listing, every .JPG file is listed as type "Unhandled Extension Handler Finder" instead of the expected 'jpg file.'

    Because the file type is incorrect (not "JPG file"), I don't get the correct contextual menu when I right click on an image file. That means I can't open "properties" to view or edit the fields I need, like the tags and comments, and I need to!

    I saw a thread here from a person that posted the same problem back in 2018, but neither the cause of the problem, nor the solution he came up with. apply to me.

    So I'm stumped! Can anyone help?

    Windows version: 1903 Build: 18362.836

    Unhandled Extension Handler Finder?

    Yup, I already did that in 'Choose default applications by type'.
    JPG, PNG & TIF are set to Windows Photo Viewer but beneath item in the list of file types Windows lists their default application.
    For example .PDF has a description of Adobe Acrobat Document followed by the application - in that case it is of course Adobe Acrobat Reader.
    However, .PNG (& other common graphic files) is described as Unhandled Extension Handler Finder followed by the application Windows Photos Viewer.
    I can readily change the default application but it makes no difference to the description/type: Unhandled Extension Handler Finder

    Unhandled Extension Handler Finder?

    OK, well the cause of this problem is due to the attempt to restore the sadly missed 'Windows Photo Viewer'. The procedure as outlined in TenForums tutorial: 'Restore Windows Photo Viewer in Windows 10' causes image file types to be listed as 'Unhandled Extension Handler Finder.
    It's a damn shame because I much prefer 'Photo Viewer' over 'Photos'.
    If there's another method of restoring 'Photo Viewer' without the file type problem I'd be happy to hear it.
    Thanks folks.
