Windows 10: Cannot Change Default Apps

Suddenly I cannot change what apps are defaulted to open.1 I change it in settings, it shows it has changed, but ignores the change and opens with the original app always.2 "Open With" pops up a list of apps. It used to be that if I selected "Choose another app", I got a check box that said "Always use this app". That checkbox never appears anymore.3 Several file extensions never show up in the change default by file type. For instance, real biggies like MPEG, MPG, MP4, AVI, GIF, JPG, JPEG are not on the list.4 Selecting the group "Media Player" also does not populate with any of the biggi

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.

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

 

How to change default app for file type

@Bree - yes, I'm quite aware of this thanks, but as you will see it's missing. I recall reading that clicking the dialogue at a certain point in blank space made it appear, and trying that once successfully, but doesn't seem to help now. Plenty of other similar reports of this option being missing.

Cannot change the default apps by using control panel

Original Title: Cannot change default apps.

As said, I cannot change the default apps by using control panel > ... > Default Apps tab.

I cannot change any of the default programs. I use paint.net to edit/view photos and I cannot set it to the default program even though it is on the list, it does not change and i'm stuck with the default photo viewer. This happens with any other app actually,
I cannot change the default music player there, nor browser or anything.

I followed these steps as suggest by a microsoft engineer, post 2, and later on, no avail.
