I know this topic is ancient. I have a dimension to add though: when installing Paint.net via the Microsoft Store the app gets written into the hidden (and inaccessible) folder c:\program files\windows apps\
I know you can access this folder through manipulating its security settings. But I am on a machine where I cannot/do not want to do that.
But I can (and want to) change the default photo editor app via the registry hack mentioned by peterfnet (posted January 7, 2017). So what target do I point the registry to?
Something C:\Program Files\WindowsApps\....? Any ideas?
