What it means
A trusted free tool that scrubs every trace of a graphics driver so you can install a fresh one cleanly. It's the "factory reset" for your GPU driver.
More detail
DDU stands for Display Driver Uninstaller. You don't need it for routine updates — those install fine on their own. Reach for it when something's actually wrong: weird artifacts, a botched install, or switching graphics card brands. Run it, then install the vendor's current driver.
