Windows 10: Cannot change default apps

Windows 10 Education Version 1803, OS build 17134.345


I cannot change the default apps for opening files with the extensions .ai and .R. I have checked the obvious stuff, such as creating a new user profile, restarting the PC, trying to change it via Open with... - nothing worked.


I contacted customer support twice. The first time, an inplace upgrade was recommended. Upon trying this I received the error message that my version of Windows is not supported.


The second tech did a system recovery without my explicit prior consent, resulting in the loss of several programs. This is utterly unacceptable.


The problem still persists.

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.

Can't change default apps in Windows 10

I refuse to use work arounds, I'd like a proper solution is possible, thank you.

 

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.

 

Windows10 Keeps Changing my Default Apps

Hi Carol,

There is a certain option in Settings where you can change the default apps for a specific file type. For example, your .psd file can be opened by a certain app as a default while the other file types can be opened by a different app. You can manually change
it by following these steps:

• Press Windows key + I.
• Select Apps, and then Default apps.
• Select Choose default apps by file type.
• From there, scroll down to the file type that you want to change the default app.
