RE: About unloading drivers and system shutdown

It does not look like you ever got this question answered.

The answer is no. The system does not attempt to unload drivers at
shutdown time.

For “net stop driver” to work you must have defined a DriverUnload
routine. You may want to look at the new sfilter and filespy examples
in the WindowsXP IFSKit. It shows how to do this properly.

WARNING: Unloading a filter is not a supported feature. Though you can
make it work most of the time and it is convenient during development,
it is not a feature that should be in a released filter.

Subject: [ntfsd] About unloading drivers and system shutdown

Hi guys,

I was wondering about unloading filter drivers… I know that basically
this should be prevented, but the question is the following.

Suppose my driver faults at unload time if I call “net stop driver”.
Would
my driver fault in the same way if the operating system is shut down ?
In
other words, does a system shutdown include the same functionality as
“net
stop driver” ???
