CBS allows components and features from IIS to Windows Media Player to be packaged as small modules that encompass the full functionality of the component. Users benefit from a more complete and controlled installation process that allows updates, drivers and optional components to be added while simultaneously mitigating against instability issues caused by improper or partial installation. The CBS architecture is far more robust and secure than the installers in previous operating systems. In Windows Vista, the new componentization architecture, known as Component-Based Servicing (CBS) changes the way that these components are installed. Prior to Windows Vista, if you wanted to install optional components, Windows Updates or driver files on your system, the process was fairly simple. First published on TECHNET on Apr 23, 2008
