Explanation
From an end-user's perspective in Windows Installer, a Feature is the smallest selectable unit they see and can choose to install. Users select features like 'Documentation', 'Application Core', or 'Tools' in the installation tree. Features are composed of one or more components, but components are developer-level constructs that users don't directly interact with.
