Hi
quick question: can wmi be used from a legacy (ie: non-wdm) driver?
The doc says that the wmi library is an extension to WDM but I would like to
know if anybody has tried to get it to work with a legacy driver or if it is
a waste of time trying to.
More specifically, we would like to use wmi to 1) Notify user-mode
applications of driver-defined events , and 2) make custom data available to
user-mode applications.
cheers,
Yes, it can be done. Wmilib can be used as well, but in places where
you are indicted to forward the irp down the stack, you need to complete
it immediately (since there is no stack). Also, you will need to use
static instance names b/c you have no PDO to rely on for naming.

WMI does not require PnP or PDOs. Works fine in FS filter.
