Re: whether a driver is running in user- or kernel- mode

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Which particular output should I be looking at to tell whether it's in user-
or kernel-mode? I'm having trouble regarding this area. Would that be
observing the behaviour on DrvQueryInfo callbacks?

there any specific way (perhaps with a debugger) to tell whether it's running

You can use WinDbg in verbose mode.
