The Windows Installer organizes an installation around the concepts of components and features.
A feature is a part of the application's total functionality that a user may decide to install independently. For more information, see Windows Installer Features.
A component is a piece of the application or product to be installed. The installer always installs or removes a component from a user's computer as a coherent piece. Components are usually hidden from the user. When a user selects a feature for installation, the installer determines which components must be installed to provide that feature. For more information, see Windows Installer Components.
Authors of installation packages need to decide how to divide their application into features and components. The selection of features is primarily determined by the application's functionality from the user's perspective. Because components commonly must be shared across applications, or even across products, it is recommended that authors follow a standard method for selecting components. For more information, see Organizing Applications into Components.
