title: Is it possible to unload a kernel driver without a reboot?
body: <p>I'm playing about with one of the kernel driver examples in the Win7 DDK. I can modify compile and build my *.sys file. I can install it too with its INF (using device manager or devcon) or using the Service control manager directly. When I make the next change though and generate an updated *.sys file I seem to get a conflict between this new file and my now stopped driver (I've tried using Servcie Control Manager 'stop' and 'delete service' etc). If I reboot, I can install the new driver and run it fine. Similarly, if I choose uninstall in Device Manager, Windows prompts me to reboot.</p>
  
  <p>So, how can one easily test incremental modifications to a kernal driver easily?
  Thanks </p>
