You don't need any mod to set the good old photoviewer as the default viewer.

You just need to set it using the provided default applications setting.

Whatever you can just use winaerotweaker to reduce the clicks needed to accomplish the task.

Thanks l33tissw00t.

Indeed, the only logical explanation for the odd happenings is that the particular registry mod I chose, though from a reliable source and apparently well tried, was for some strange reason not appropriate for my system. Consequently, I’ve restored the system to what it was before applying the mod.

So now I’m after another mod. The trouble is that, in addition to the one kindly provided above, several threads on the subject give different mods, ranging from 0.815 to 36 kB! As I’d hate to have to try them one by one, does anybody have a better suggestion?

I didn't create it, so I don't have much to offer. However, I can tell you, that if I downloaded it, I made sure it was reliable first, and you can trust it.

Anyway, good luck!

ETA:
Just saw someone posted above me with suggestion to use Winaero Tweaker - I do remember reading then that this was a good option as well.

I do need a mod, because my W10 was fresh install, and the Windows Photo Viewer, though existing, it’s not visible anywhere. I did think of all-in-one tweakers, but thought it better to avoid installing another program just for a (simple) mod. However, it may be a sure-fire solution.

Thanks for coming back with the assurance. I’ll now wait till tomorrow for trying again.

Is there. Hard to find but is still there.

Whatever winaerotweaker is worth for another zillion of things, and it doesn't mess anything. Everything can be reverted, everything is useful.

Give it a try.

I just use a script PhotoViewer.reg, last added s few build ago and taken over automatically since!

Used the following and merged into Registry:

Code:

Windows Registry Editor Version 5.00

; Change Extension's File Type
[HKEY_CURRENT_USER\Software\Classes\.jpg]
@="PhotoViewer.FileAssoc.Tiff"

; Change Extension's File Type
[HKEY_CURRENT_USER\Software\Classes\.jpeg]
@="PhotoViewer.FileAssoc.Tiff"

; Change Extension's File Type
[HKEY_CURRENT_USER\Software\Classes\.gif]
@="PhotoViewer.FileAssoc.Tiff"

; Change Extension's File Type
[HKEY_CURRENT_USER\Software\Classes\.png]
@="PhotoViewer.FileAssoc.Tiff"

; Change Extension's File Type
[HKEY_CURRENT_USER\Software\Classes\.bmp]
@="PhotoViewer.FileAssoc.Tiff"

; Change Extension's File Type
[HKEY_CURRENT_USER\Software\Classes\.tiff]
@="PhotoViewer.FileAssoc.Tiff"

; Change Extension's File Type
[HKEY_CURRENT_USER\Software\Classes\.ico]
@="PhotoViewer.FileAssoc.Tiff"

If need more file types, just add them accordingly!! Maybe need to add Photo Viewer as Default in Settings again!

Works fine for me.

UPDATE

After the first erratic attempt to restore the old Windows Photo Viewer, I’ve made a new attempt. This time, I chose the simplest mod, also used by the late and much respected EFA11. This is essentially the same as posted by pisthai in post #9, but from which the first line is missing.

The full mod is:
Code:
Windows Registry Editor Version 5.00

; Change Extension's File Type
[HKEY_CURRENT_USER\Software\Classes\.jpg]
@="PhotoViewer.FileAssoc.Tiff"

; Change Extension's File Type
[HKEY_CURRENT_USER\Software\Classes\.jpeg]
@="PhotoViewer.FileAssoc.Tiff"

; Change Extension's File Type
[HKEY_CURRENT_USER\Software\Classes\.gif]
@="PhotoViewer.FileAssoc.Tiff"

; Change Extension's File Type
[HKEY_CURRENT_USER\Software\Classes\.png]
@="PhotoViewer.FileAssoc.Tiff"

; Change Extension's File Type
[HKEY_CURRENT_USER\Software\Classes\.bmp]
@="PhotoViewer.FileAssoc.Tiff"

; Change Extension's File Type
[HKEY_CURRENT_USER\Software\Classes\.tiff]
@="PhotoViewer.FileAssoc.Tiff"

; Change Extension's File Type
[HKEY_CURRENT_USER\Software\Classes\.ico]
@="PhotoViewer.FileAssoc.Tiff"
This mod worked better and fully restored WPV as an option in both Default Apps as well as by right clicking an image. I consequently consider this as the optimum to use by anybody interested.

BUT
Though the WPV displays GIF files, including transparency, it doesn’t show the animation. Thus, it is not of much use to me. Can someone who restored Windows Photo Viewer try it on an animated GIF image and inform me if it works properly? If it does, which mod did he use?

This isn't a Windows 10 issue. WPV never supported animated gifs and considering MS wants to replace WPV with a metro app I think it's safe to say that it won't ever be supported. If you want to open animated gifs you'll have to use a web browser or a different photo viewer.

Thanks for the clarification and for answering my question that everybody else ignored. I never used Window 7, but can assure you that the Photo Viewer of my XP fully supported animated gifs, as well as other common formats.

If, however, the Windows Photo Viewer included in 10 (after restoration) does not support animation, something that I find odd, then it's useless and not worth wasting anybody's time. Especially since the new Photos app does support GIF animation. Its only weakness is that is doesn't show GIF transparency, but which is of minor importance in comparison.

I also find it strange that in so many posts in so many threads, also websites, I've seen knocking the Photos app and praising WPV, nobody mentioned this important shortcoming of the latter.

I believe since Vista days WPV never supported GIF so...
I used to have Irfanview in W7 to see animated gifs.

As if animated gif is the most important graphics format...
