In phone based technical support call centers the term “Ghost Driver” gets used a lot. A Ghost Driver is a funky thing Windows does. In the device manager you will see one version of a certain driver; lets say for your NIC card. Assume the NIC card is not working and you think it is the driver.

A ghost driver is also a term used in Germany. In Germany a ghost driver is someone who drives towards on coming traffic on the Autobahn.
