Add/Remove Hardware Wizard doesn't work...

I am trying to modify the source code of FileMon to implement a program
which block a certain process’s file I/O request.
I found that everytime I start the FileMon, the filter driver installed to
the Windows 2000 automatically, even I remove it by using Windows’s
Add/Remove Hardware Wizard, it is still in the memory and it only
disappear after reboot. This slows down my development process.
Can it be avoid?
