Default Programs

To open a particular type of file, such as a music file, an image or a web page, Windows uses a default program. In this dialog, a specific program can be set as default for a specific file type.

Caution!The Default Programs feature applies only when the package is installed on Windows Vista or later. For lower systems, it's ignored.

Caution!The Default Programs feature does not apply on Windows 8 and newer operating systems. Due to their design, these operating systems don't allow setting the default programs programmatically.
