This section describes kernel-mode Windows Management Instrumentation (WMI) extensions to WDM. When you add these extensions to your kernel-mode driver, your driver becomes a WMI provider. A WMI provider makes measurement and instrumentation data available to WMI consumers, such as user-mode applications.

For more information about the user-mode WMI API, refer to Windows Management Instrumentation in the Windows SDK.

If you are implementing a KMDF-based driver, refer to Supporting WMI in Framework-Based Drivers.

This section includes the following information about kernel-mode WMI:
