Windows 10: Why does Windows 10 keep changing my default apps?

In the past my default apps would reset every 6 weeks or so - now it is happening within a matter of two hours. This is super frustrating.

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.

 

Windows 10 1803 default app change bug

When right clicking a file and going to "Open With", no matter what file it is, I can't change its default. The box is checked, and the app doesn't change.

This is also true of right clicking and going to "Properties". When I click change, the default doesn't change.

This is happening to me on 3 computers now. Steps to reproduce? I could probably do it by:

Installing Windows 8.1, and upgrading to 10 with the media creation tool.

This does not happen with a fresh install from a USB with Windows 10.

Don't tell me to go to "Settings" and change the defaults. The file type list is horrible, and some of my file types are not listed. The registry is not an option on multiple PCs as it is not just one file type. It is ALL file types. No matter what one I
try, it's always the same result.

Are there any suggestions? I know how to navigate computer, so please do not suggest that I need to go to Settings

> Apps > Default Apps. These options are far from optimized, and they don't have what I need. There isn't even an option to browse for an app to select defaults for when the app doesn't show up in the list.

A quick fix would be nice. Even a simple item in the registry? I could potentially have this problem on all 75 computers in this building as they all started at 8.1 before going to 10. I can't reinstall Windows on every machine. That's ridiculous.

 

Windows 10 forgets default apps

I have noticed like not 5mins ago that Winamp just got kicked out of my default apps list in Windows 10 Pro.
I installed this installation not max 3 weeks ago with fresh downloaded Windows 10 Pro using Microsoft Media Creation Tool, is there a way to fix this bcs I using sfc /scannow don't do a lot for me and I have run it before on this installation.

Before u ask, I have fully updated my Windows 10 with all non-insider/beta updates.

The only thing I have disabled is the uac prompt that popup when u need admin for applications to run bcs it's simply annoying.

I don't remember having all these problems with Windows 8.1 Pro when i was using that and I am really thinking about going back so I can have "fully control" over Windows again with like disabling all the admin crap bcs I feel like it's messing more up and makes things less useful in Windows 10 with all these small problems I have and I read a lot of ppl having problems with various things time and time again where they needed to reinstall Win10 over and over to get it to work fully.

Any advice on how I can get Windows 10 to just work as a "daily driver" without all these small annoying things? *Frown
