Windows 10: Photo viewer suddenly has a border with every image if not started from the photo viewer app

I've been going crazy with Photo Viewer, this is an issue that reared its head only 2 days ago... I genuinely do not know what happened. So here is my problem:Note the border around the picture despite it being set to "full screen" F11, the border is dark because I have things on dark mode.Anyhow, LITERALLY THREE DAYS AGO full screen would do this:Note how the image takes up ALL of the screen space when F11'ed. I don't know what I did, I've checked every setting I possibly could, checked every menu. I know its not "that big a deal" but its absolute frustration and its bugging me to no end. N

Replacement for photo viewer

I just use the Photos app for a quick view, otherwise I use Adobe Lightroom to view and edit photos.

 

How to bring back Photo Viewer in Windows 10?

Unfortunately, none of the above answers worked for me, but they pointed me in the right direction.

1. Right-click on an image in Windows Explorer, choose Open With, then Choose another app.
   
2. In the dialog, scroll down and click on More apps, then `Look for another app on this PC.
   
3. Then, at the bottom right, choose All Files (*.*) instead of Programs (*.exe ...), then navigate to C:\Program Files\Windows Photo Viewer and choose PhotoViewer.dll.
   
4. Photo Viewer opens. Close it.
   
5. Repeat Step 1: Right-click again on the image, choose Open With, then Choose another app.
   
6. Again scroll down to click on More apps.
   
7. Now Windows Photo Viewer appears in the apps list. Choose it and click on Always use this app to open .png files.
   

Once you did steps 1-4, you don't have to repeat them for other file types. Steps 5-7 should suffice.

 

Unable to replace Photos app with Photo Viewer as default (10240).


I'm not making any headway on answers.Microsoft.com so I'm hoping the experts here can explain why I cannot replace the Photos app with Windows Photo Viewer as the default image viewer (in build 10240). From all outward appearances, it seems Windows Photo Viewer is unavailable.

The saga is explained in detailed words and colorful pictures here:

If that's too tl;dr for you, here are the bullet points:

• Windows Photo Viewer is never listed as an option when using "Open with".
• "Open with" lets you browse the disk and manually select the desired program. I navigated to "\Program Files\Windows Photo Viewer" but it contains no program there other than "Imaging Devices" (wrong). Choosing "PhotoViewer.dll" produces an error message.
• In Control Panel's "Default Program", Windows Photo Viewer is shown to be associated with TIF files and nothing else. Attempts to set JPG to use Windows Photo Viewer fail because, again, its program folder only contains "Imaging Devices" (and the dll).

In an attempt to fix this problem, I used the "nuclear option" and Reset the PC. After Windows 10 (TH1 10240) reinstalled itself, I still couldn't select Windows Photo Viewer to be the default image viewer.

Suggestions to fix this?
