The shell extension is assigned to the incorrect application either by user interaction, programmatic or through malware.

You can manually change them
  • Press [Windows Key + i]
  • Click Apps
  • Click 'Default Apps'
  • Here you can change primary applications, or for specific file types click 'Chose default apps by file type'
  • Locate the file type and select the desired application
