Windows Management Instrumentation
Windows Management Instrumentation (WMI) is the infrastructure for management data and operations on Windows-based operating systems. You can write WMI scripts or applications to automate administrative tasks on remote computers but WMI also supplies management data to other parts of the operating system and products, for example System Center Operations Manager, formerly Microsoft Operations Manager (MOM), or Windows Remote Management (WinRM).
WMI can be used in all Windows-based applications, and is most useful in enterprise applications and administrative scripts.
WMI is designed for programmers who use C/C++, the Microsoft Visual Basic application, or a scripting language that has an engine on Windows and handles Microsoft ActiveX objects. While some familiarity with COM programming is helpful, C++ developers who are writing applications can find good examples for getting started at Creating a WMI Application Using C++.
To develop managed code providers or applications in C# or Visual Basic .NET using the .NET Framework, see WMI in .NET Framework.
Many administrators and IT professionals access WMI through PowerShell. The Get-WMI cmdlet for PowerShell enables you to retrieve information for a local or remote WMI repository. As such, a number of topics and classes, especially in the Creating WMI Clients section, contain PowerShell examples. For additional information on using PowerShell, see Windows PowerShell and Scripting with Windows PowerShell.
For more information about which operating system is required to use a specific API element or WMI class, see the Requirements section of each topic in the WMI documentation.
If an expected component appears to be missing, see Operating System Availability of WMI Components.
You do not need to download or install a specific software development (SDK) in order to create scripts or applications for WMI. However, there are some WMI administrative tools that developers find useful. For more information, see the Downloads section in Further Information.
