The Windows 95 Registry contains file-extension associations that automatically launch the appropriate application when you double-click on a particular file type. However, older applications can sometimes reclaim file extensions, even though the Registry associated a different program with them. That's because whenever Windows 95 starts up, it automatically reads into the Registry the file-extension associations stored in WIN.INI. Although the WIN.INI file isn't needed by Windows 95, it's kept around for
compatibility purposes. One way to prevent WIN.INI from overriding the Registry's autolaunch preferences is to delete the file-extension associations in WIN.INI. Open WIN.INI in Notepad, scroll down to the [Extensions] section, and remove any lines that conflict with Registry associations.
