Windows 10: How to add programs to the Default Apps list?

I mean the list that shows up when you go to Settings > Apps > Default Apps. You can "Look for an app in the Microsoft Store", but I want to add a .exe. I know you can set default apps by file type or protocol, but this is much easier and I don't have to set them one by one and maybe even forget a format.

Using Windows 10 Build 19042.631.

Lost default photo viewer after profile rebuild

Thanks Brink. I've tried those steps before i started searching Google. After the profile rebuild i don't have the Photo app listed to choose to make it default in either the system settings for default apps or the Open With option.

I can't even find it doing a search. Seems to have been removed somehow with the profile rebuild, which doesn't make sense.

Might be helpful to list what i've done I've done the open with check, the choose default program in the system menu, tried that in device manager default programs also. I've checked the programs and features Turn windows features on/off and it's not listed there (never thought it was but that was a suggestion), searched the MS Store, it's not listed there either.

I don't like playing in the registry unless i have defined steps and haven't found anything for this yet, just the Win7 version like in my OP.

 

Programs Missing From Control Panel List

I was able to get rid of XNVIEW by downloading it and using it's own uninstaller.
Have tried method suggested by Pyramid 10 with photoscape without success.
Can't figure out how to do what is asked.

Your next suggestion?

 

Adding programs to the list of Default Apps

...actually this does solve the problem. After doing the steps "Open With" from File Explorer, clicking "More Apps", selecting Kodi. Then the next time when I go to "Default apps", "Choose Apps", now Kodi is included in the list.

This feels like a strange workaround, but it works.
