Component Management: Windows Installer provides structured component management for applications. Components are the individual parts of an application, and Windows Installer allows precise control over their installation, repair, and removal.
Patch Management: Starting from Windows Installer 3.0, multiple patches can be installed in a single transaction, ensuring rollback capability if issues arise during patch installation.
Administrator Privileges: Users with administrator privileges can use Windows Installer's API to query and manage product information, features, components, and patches, streamlining software management.
Security Features: Windows Installer 5.0 and later versions enable installation packages to define security settings for files, folders, registry keys, and new accounts, enhancing installation security.
Customization: Developers can create installation packages tailored for different installation contexts, whether per-machine or per-user.
Compatibility: It's designed to work seamlessly with various Windows OS versions, with different redistributables available for different Windows Installer versions.
Overall, Windows Installer provides a standardized framework for software installation and management on Windows, offering reliability, security, and flexibility for software installations and updates. It's a vital tool for developers and system administrators working with Windows-based applications.
