WMI Driver Extensions
The WMI extensions to WDM provide kernel-level instrumentation such as publishing information, configuring device settings, supplying event notification from device drivers and allowing administrators to set data security through a WMI provider known as the WDM provider. The extensions are part of the WDM architecture; however, they have broad utility and can be used with other types of drivers as well (such as SCSI and NDIS). The WMI Driver Extensions service monitors all drivers and event trace providers that are configured to publish WMI or event trace information. Instrumented hardware data is provided by way of drivers instrumented for WMI extensions for WDM. WMI extensions for WDM provide a set of Windows device driver interfaces for instrumenting data within the driver models native to Windows, so OEMs and IHVs can easily extend the instrumented data set and add value to a hardware/software solution. The WMI Driver Extensions, however, are not supported by Windows Vista and later operating systems.

Famous quotes containing the words driver and/or extensions:
“God help the horse, and the driver too!
And the people and beasts who have never a friend!
For the driver easily might have been you,
And the horse be me by a different end!
And nobody knows how their days will cease!
And the poor, when they’re old, have little of peace!”
—James Kenneth Stephens (1882–1950)
“The psychological umbilical cord is more difficult to cut than the real one. We experience our children as extensions of ourselves, and we feel as though their behavior is an expression of something within us...instead of an expression of something in them. We see in our children our own reflection, and when we don’t like what we see, we feel angry at the reflection.”
—Elaine Heffner (20th century)
