About this tag
Application association in Windows refers to the system that links file types or protocols to specific programs. Common issues include default email clients not being recognized, such as Gmail or Thunderbird, due to missing or empty registry entries for protocols like 'mailto'. Users may encounter errors when trying to send emails from file context menus. Additionally, file type icons and application associations may fail to update on Windows 7 64-bit systems after registry edits, even after using SHChangeNotify to refresh the shell. Troubleshooting often involves checking default programs settings, registry protocol branches, and ensuring proper association updates.
