The Best FREE WMI Monitor Tools for Windows Server and Desktop

We Review the Best free Wmi Monitor Software

Marc Wilson UPDATED: August 29, 2023

WMI, or Windows Management Instrumentation, is a Microsoft technology for the management of Windows-based workstations and servers. WMI allows network administrators to monitor performance and view or update configurations of Windows computers from a single management interface.

WMI is has a lot in common with SNMP, or Simple Network Management Protocol. SNMP is an older management technology that is still widely used for monitoring and management tasks.

Unlike SNMP, WMI is a proprietary technology from Microsoft, and is specifically designed for Microsoft-based networks, servers and workstations. It is enabled by default on recent Windows machines, and can provide more detail and manageability than SNMP.

Its power, flexibility and ubiquity makes WMI a great choice for managing Microsoft networks and Windows workstations and servers. WMI tools come in many different flavors for many different needs, but here are five of the best that provide great features for free or nearly free.
