Printers drivers can be removed by going to [Control Panel] and double click the [Printers] icon. In [Printer] window, click to select the printer you want to remove and press [Del] key to remove the printer driver.
If you want to remove driver files used by the system hardware, run [Device Manager] and bring up that device's properties. Bring up the [Driver] tab, copy the list where the driver files are from [Driver File Details] button, and delete them after you remove that device.
Note : You have to note down the driver files BEFORE you remove the device.
