Windows 10: Removing "Default App" setting from file type

I am running Windows 10. I accidentally chose a default app to open a certain type of file and now I can't set it back to "none". I do not want ANY app associated with this file type. How do I fix this? I already tried creating a dummy .exe file to associate it with and Windows won't allow me to use it. HELP!! this is so frustrating and should be so much simpler to fix!

How to change default app for file type

'Open With > Choose another app' has three step, in the first it only offers apps registered for that file type. If you click 'More apps' it lists all registered apps regardless of suitability. Both these steps have the tick-box for 'Always use...' in my 18363.752. The third step, if needed, is 'Look for another app on this PC'. The 'Always use...' must be ticked before taking this step if you want the change to stick. However, WMP appears at the second step.

For a quick look at a JPG almost anything (including WMP) is more practical than Photos which on my system takes more than ten seconds just to open a photo. The OP is probably not aware that the Windows Photo Viewer is still available in W10, but hidden away. That's my default viewer for JPG.


Restore Windows Photo Viewer in Windows 10

And, once enabled, is available in Settings > Apps > Default apps.
