In those cases, the best procedure is just to reinstall this app and leave the rest of the driver alone.

In some cases, reinstalling or updating an official driver may cause a PC to start behaving differently, especially if the driver files become damaged, corrupt or missing, or if the new driver is unstable and may lead to system freezes or crashes. However, in certain situations the access to this driver utility can be lost, forcing users either to reinstall a full driver package or to just go and find the new installation only for this app. It is important to note that the NVIDIA Control Panel Desktop is the part of every official Nvidia driver, and therefore should be automatically installed on any PC with Nvidia GPU. This includes not only generic settings tied to the current display output resolution during regular desktop work in Windows OS, but also all other aspects of the graphic generation such as managing 3D settings for video games and other 3D-accelerated apps, adjusting desktop color settings, multi-monitor tools for setting up display arrangements and rotations, handling built-in audio settings (which is used when GPU is sending both video and audio data via its HDMI port), and much more. NVIDIA Control Panel is a driver utility that can help PC users of all knowledge levels to take control of all aspects of services that are handled by their Nvidia graphics processing unit.
