Windows 10: I cannot change the default app for any type files no matter what.

Good evening.

I formatted my PC few days ago. Everything is going smooth except for the fact I cannot change the default apps of any kind of format/program in any way.

Weather I do it through the Settings, or directly on a specific file, I cannot change it.

I can open the file in a custom app, but it won't be a default app.

It didn't work for apps that were installed on C:/ or D:/


I also have 2 videos showcasing the problem.

Thanks for your help.

cannot change default app for jpg files

Hi KH,

Setting a default program or app to open a file doesn't restrict other apps or programs that support the same file type to open it. With your .jpg file opening with Photo viewer, it appears that Photo viewer is set as the default program. If you want to
use the other program as the default .jpg viewer, then let's make sure that it's properly selected as the default program. Make sure to close both your Photo viewer and Irfranview apps first before doing the changes.

To associate a file type or protocol with a program, follow the steps below:

• Open Control Panel.
• Click Programs, then Default Programs.
• In the right pane, click Associate a file type or protocol with a program.
• Locate and click .jpg extension and click the Change Program option in the upper left corner of the page.
• Select the program or app you want .jpg file to open with. If the app you want to use doesn't appear under
  Other options, then click on More apps.
• Once you've selected the app or program, click OK and then
  Close.

Try opening a .jpg file and see if it opens with your selected app or program.

Let us know if you need further help regarding this matter.

Regards.

 

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.

Feel free to contact us if you need assistance with Windows.

 

app default setting by file type

Hi Richard,

We understand that you're having issues with the default file app association on your computer. To assist you with your concern, you may refer to the steps below on how to change the default setting of your application:

• In Search Windows textbox, search for choose a default app for each type of file and set .PDF and any other file extensions to point to your choice for default
  programs. Do not use Adobe Reader to set the association.
• Navigate to %systemroot%\system32 and locate the OEMDefaultAssociations.xml file. Make a backup of it just in case.
• Open the OEMDefaultAssociations.xml file and keep it open using
  Notepad.exe.
  
• Open PowerShell or CMD and run it as Administrator.
• Enter the following: Dism /Online /Export-DefaultAppAssociations:C:\AppAssoc.xml
• Open C:\AppAssoc.xml with Notepad.exe
• Copy the entire contents of AppAssoc.xml and replace the entire content of OEMDefaultAssociations.xml.
• Save OEMDefaultAssociations.xml.
• Delete C:\AppAssoc.xml (optional).

After doing the steps, you may now change the default file app association for opening .pdf.

Do update us with the outcome and if you need further assistance.
