Uninstalling the Driver. When un-installing the driver from Windows, always
use the Add/Remove Programs utility as this uses the driver uninstaller program
to remove files and registry entries to leave a clean system. Other methods may
leave fragments of the driver, which may interfere with futureinstallations.
