Description: The Windows Management Instrumentation (WMI) service provides a common interface and object model to access management information about operating system, devices, applications, and services. WMI is an infrastructure for building management applications and instrumentation shipped as part of the current generation of Microsoft operating systems.

The WMI infrastructure is a Windows operating system component that moves and stores information about managed objects. The WMI infrastructure is made of two components: the WMI service and the WMI repository. The WMI service acts as an intermediary between the providers, management applications, and the WMI repository, placing information from a provider into the WMI repository. The WMI service also accesses the WMI repository in response to queries and instructions from management applications. Finally, the WMI service can pass information directly between a provider and a management application. In contrast, the WMI repository acts as a storage area for information passed in by the various providers.

WMI provides accessible information about applications and services, including management events those applications and services might generate.

WMI provides access to the management data through a number of interfaces, including COM API, scripts, and command-line interfaces. WMI is compatible with previous management interfaces and protocols, such as SNMP.

If this service is stopped or disabled, most Windows-based software does not function properly and management data is unavailable.
