Right click on the icon "Computer" --> click on "Manage" --> click on "Device Manager" --> right click on the damaged driver and choose "update driver software" --> choose "browse my computer for driver software" --> choose "let me pick from a list of device drivers on my computer" --> choose the folder with the adb driver and click OK. If your computer display a warning "Windows can't verify the publisher of this driver software" don't worry and click "install this driver software anyway".
