One of the most important capabilities of Windows Installer is Multiple Package Transaction. It uses a chainer to integrate packages in a transaction with multiple components. So in case not all packages are successfully installed or you choose to cancel the installation process, Windows Installer can roll back all the changes and restore the operating system to its original state.

Moreover, Microsoft Windows Installer makes it possible for an updated component to be available to all products using it, enabling installation events across multiple packages. Last but not least, setup developers can use Windows Installer to develop single installation packages capable of installing an application in either a per-machine or a per-user installation context.
