Removing Hidden drivers (non plug and play)

Do CCleaner and Defraggler install any non plug and play drivers which can be viewed under hidden devices in Device Manager? I am running Vista 64.

This information would be useful for troubleshooting or if I choose to uninstall CCleaner and or Defraggler - I want to ensure that there is no 'residue'.

Thank you in advance.

No, they don't install any hidden drivers, or any drivers at all actually.
