Not sure if this has already be mentioned but installing MS Essentials 2012 with Photo Gallery does very much what the Windows Photo Viewer once did. You can then select Open With ... Photo Gallery. I know MS Essentials 2012 is a little old now, but it works :)
As mentioned before the MS Photos app does the same thing, Open with ... Photos :)
That said the original Windows Photo Viewer was simple and good :)
