It is usually highly recommended to update your device drivers as hardware manufacturers often release new versions of their drivers for fixing bugs, adding new features, increasing device and system performance, improving computer stability, fixing compatibility with other devices and closing security holes, While most of the popular automatic Windows driver updation utilities are not free, we reviewed RadarSync as one possible free option which worked quite well for me, but failed on many computers as noted in user comments.
