Driver load/unload problem!

NTFSD
1

I changed Filemon-Code(FileMon of sysinternals.com), and I build a new
filem.sys.
Next, I ran Filemon.exe(GUI, which loading filem.sys driver).
By the way, Changed items of filem.sys wouldn’t act.
Seem to act previous-version of filem.sys.
If i run Filemon.exe(GUI) after rebooting my computer, Changed items of
filem.sys are acting.

Why does this phenomenon happen?
I want changed items of filem.sys to be applied promptly without
rebooting.

Thanks for any suggestions!
Sincerely!

Chang Sung, Jung.

The system is functioning as expected. The NT IO Manager does not
support the unloading of file system filters in a safe manner. You must
reboot your system to load a new version of your filter.

The SFILTER and FILESPY samples of the XP version of the IFSKit show you
how you can implement unload but this is only for development purposes
in DEBUG builds. A production quality filter must NOT support unload,
the system will crash periodically if you do this.
