WMI Summary
Clearly, the implementation of WMI can be involved. At this point in the evolution of WBEM and WMI, the payback is minimal. The addition of WMI support to a driver is a plan for the future. The ultimate acceptance of WMI (and WBEM in general) remains to be seen.
A WDM driver is not required to support WMI. It can use the conventional method of logging system events for notification messages, which is described in the next section. For data collection (instrumentation), the registry or custom IOCTLs can be utilized.
