my DYNEX DX-USBMIC13 hasn't been working, so i uninstalled the driver through device manager. i reinstalled it and it still didn't work (windows vista auto installs the driver) so i thought i'd make sure it was really uninstalling. i copied down the files of the driver, and after uninstalling again looked them up in search. sure enough, every file was still there. how do i get rid of this driver and all of its files completely? is there a program that can do this? is it safe to manually remove them from system32? any help would be appreciated
