Windows 10: Change default app for all supported extension all at once on windows 11

I did not find any posts about this and it surprises me. On Windows 7 and Windows 10, there was a button to make a program default for every file format it supports. So when I installed a media player, I clicked one button, and it associated every audio and video format. On Windows 11 how can I do this? On the default app settings, there are just extensions I can choose from. Obviously, I don't want to search for a hundred different extensions one by one, I want my media player/image viewer, etc to associate with everything it supports. What is the way to do this?Thanks :

On the left, search for .res extension

Across .res extension, tap on Choose a default

Try browsing for the app.

Change default file extension for application

I am using the windows 11 photo app. The default file extension is .NEF. Is there a way to change this to .TIFF or some other format? I use a photo editing tool that will not open .NEF and it means exporting the file and saving as to change the extension. I would like the Windows Photo app to default when opening any/all files to the .TIFF extension.

Thank you in advance.
