I just have nHancer running in services.msc as "automatic".
The service remain active all the time, it doesn't do anything by itself. Only the nHancer application should be shut down during a driver (un)installation.
And to avoid any error messages, it's better to disable the autostart of nHancer, because you need several reboots until the new driver is up and running.
