Windows Management Instrumentation


Windows Management Instrumentation (WMI) consists of a set of extensions to the Windows Driver Model that provides an operating system interface through which instrumented components provide information and notification. WMI is Microsoft's implementation of the Web-Based Enterprise Management (WBEM) and Common Information Model (CIM) standards from the Distributed Management Task Force (DMTF).

WMI allows scripting languages (such as VBScript or Windows PowerShell) to manage Microsoft Windows personal computers and servers, both locally and remotely. WMI comes preinstalled in Windows 2000 and in newer Microsoft OSes. It is available as a download for Windows NT,Windows 95 and Windows 98.

Microsoft also provides a command-line interface to WMI called Windows Management Instrumentation Command-line (WMIC).

The purpose of WMI is to define a proprietary set of environment-independent specifications which allow management information to be shared between management applications. WMI prescribes enterprise management standards and related technologies for Windows that work with existing management standards, such as Desktop Management Interface (DMI) and . WMI complements these other standards by providing a uniform model. This model represents the managed environment through which management data from any source can be accessed in a common way.
