What are Free System Utilities?
System utilities are specialized software tools designed to maintain, manage, and optimize computer systems. They assist with essential tasks such as file management, disk cleanup, backup, performance monitoring, and troubleshooting. 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.
