Restore Windows Photo Viewer in Windows 10  

Hi, guys!..:)

The TenForums .reg files are really elaborate, while -some- others aren't as expansive. Are there any particular reasons for this, other than what we can see being added in the .reg files?

... The difference being that the TenForums' .reg file is adding the following File Types, so that they'll be (automagically) recognized when double-clicking; and so that the default won't be the Open with... dialog?!

Code:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Photo Viewer\Capabilities\FileAssociations]
".cr2"="PhotoViewer.FileAssoc.Tiff"
".jpg"="PhotoViewer.FileAssoc.Jpeg"
".wdp"="PhotoViewer.FileAssoc.Wdp"
".jfif"="PhotoViewer.FileAssoc.JFIF"
".dib"="PhotoViewer.FileAssoc.Bitmap"
".png"="PhotoViewer.FileAssoc.Png"
".jxr"="PhotoViewer.FileAssoc.Wdp"
".bmp"="PhotoViewer.FileAssoc.Bitmap"
".jpe"="PhotoViewer.FileAssoc.Jpeg"
".jpeg"="PhotoViewer.FileAssoc.Jpeg"
".gif"="PhotoViewer.FileAssoc.Gif"
".tif"="PhotoViewer.FileAssoc.Tiff"
".tiff"="PhotoViewer.FileAssoc.Tiff"

That's all the difference, right?? & Please excuse me if I'm being captain obvious, tnx! (Really, I'm just asking! :))

THANK YOU! OMG That PHOTOS app was driving me insane.

When Windows Photo Viewer is restored and set as the default image viewer, the right-click context menu entry is "Preview" to open with Windows Photo Viewer, correct? As opposed to when Photos is set as the default image viewer, then Edit with Photos is the context menu entry to pen. Thanks!

Ok got it. So the Image Preview right-click context menu is restored along with Windows Photo Viewer when set as default, correct? Without having to add the right-click menu entry into the registry.

Perfect. Thank you!
