Display Driver Uninstaller is a third-party cleanup utility intended to remove leftover graphics-package files, services, and registry entries that the normal vendor uninstaller may leave behind. People usually encounter it while changing GPU brands or recovering from a damaged display installation. The commonly recommended workflow is to create a restore point, obtain the replacement package first, disconnect from automatic updates if necessary, and run the cleanup from Safe Mode so active graphics files are not locked. This is a recovery tool rather than a routine updater. Use it only when a standard uninstall or rollback has failed, and obtain it from its recognized publisher rather than from a download mirror.
