Windows 10: Why can't I change the "Associate a file type or protocol with a program" on Windows 11?

When I have a .jpeg attachment in email using Outlook it tries to open in the Notepad program, freezing up the program. I can't find how to stop opening it in Notepad and choose the correct Program.

Hi Fred,

I understand that you are facing issues associating a particular file extension with a program on Windows 10. I apologize for the inconvenience caused to you.

To assist you better, please provide the information:

When you say that "Default Program Associations", are you referring to the list of default applications in default programs settings?



I want you to be informed that all the file extensions is listed in the default program settings which is displayed under
Associate a file type or protocol with a program.



In default program list, all the programs or application will be listed. Then we can select each program as default program for opening a particular file.

I suggest you to refer to the below steps to make default program for a particular file extension.

1. Type "Control Panel" without the quotes in search box and click on it.

2. Click on Programs.

3. Then click on Default Programs and click on Choose Default for this Programs.

4. Select .flv file from the list.

Also you can try other steps to associate the a particular extenstion with the program.
