Windows 10 installation broke some of my system associations. When I run some of broken apps, they often show a message, that they are not default anymore, proposing to make them default again.
However, if I choose to restore "defaultness", I get special Windows 10 message
If I follow its instructions, I get into stupid GUI, allowing me to change something, but without any ability to decide, what to change.
For example, the list of file extension associations contain no search feature, so I am unable to find which association I wish (program wish) to change.
How to overcome? Is it possible to let programs to restore associations in old way?
UPDATE
Note that the message appears when you run SOME APPLICATION. You don't know any file extensions or class names, associated with it. You know just application name, nothing more.
So the task is not to change FILE associations, but APPLICATION associations.
