how do you remove drivers with out having to roll back your pc is there an app that will do it for me ?

select the hardware you wish to remove (right click) and left click UNINSTALL. This will remove the hardware as well as any drivers for the hardware.

soon as i plug the device back in it finds the old drivers again :( i need to purge them from my system some how :(

Boot into safe modem and delete the device driver.
Windows "should" now stop finding the old driver.
