How do you quit a Hardware installation wizard?

Simply cancel the wizard. Hit "cancel" or shut the window down by hitting the "x" ontop of the window. Windows will try to install the hardware everytime it gets found again. So when you don't want to install a certain hardware, install it without a driver and de-activate it. When the hardware is found again and again, the first installation was messed up. Then you will have to install it one time with everything the driver needs. But that's a rare condition.
