How to Disable Quicktime As the Default Player in Windows Explorer


Apple QuickTime media player can set itself as the default player for a wide range of file types when it is installed. MOV is the standard QuickTime video format, but dozens of file formats may be associated with QuickTime. For example, QuickTime can view and play image types (BMP, JPG, PNG), video (AVI, MPG), and audio (MP3, WAV) and may be set to the default viewer for any of these types. Later, you may decide you want to keep a particular file type from opening automatically in QuickTime, or use a different program instead.
