Unlike applications built for end-user productivity, system utilities work behind the scenes to improve efficiency, stability, and security of the operating system. They can be built into the OS or installed as third-party tools to extend functionality. By automating maintenance and diagnostic tasks, system utilities help prolong system lifespan and ensure smooth day-to-day operations.
