Some invalid devices data will still remain in system after you replace or unplug devices. This tool can help you to clean the invalid devices data entirely from your system.

Click 'Toolkit' --> 'Clean Invalid Device' to run

Choose the device data that you need to clean up, then click 'Next'

Note: All external devices such as USB portable hard disk, printer and scanner will be regarded as invalid devices. You don't need to clean these device data if these devices still be used in the future.
