How to kill driver process ?

Hi

I am debugging some driver, I build and replace its sys file in
system32\drivers.

I find that I should reboot Windows to see new debug messages. If I remove and
add this device, or disable then enable it, I cannot see new debug messages.

Is there any way or tool to clean driver process, I have seen other driver
which
do not need to reboot Windows, what's the root cause ?

Thank you .

What kind of driver? As long as you have a DriverUnload routine, your
driver shoul be unloaded when disabled, so the next load gets the new copy.

A driver isn't a process, there isn't any memory isolation which would allow
you to force unload it. You have to design the driver to detach itself so
it can be unloaded.
