WMI, or Windows Management Instrumentation, is a Microsoft technology that provides a standardized way to access management information in an enterprise environment. It allows system administrators to monitor and control various aspects of computer systems, including hardware, software, and network configurations, through a consistent interface. WMI uses a set of specifications and protocols to enable communication between different software components. This makes it easier to automate tasks, gather system information, and manage resources across multiple computers, enhancing overall system management and performance in Windows operating systems.
