Overview – Disable Delivery Optimization
Windows Delivery Optimization service (also known as Windows Update Delivery Optimization, WUDO and Delivery Optimization Service, DoSVC) is responsible to assist users in downloading Windows updates from other devices on the same network and then distributing them to those devices at a later time. This method conserves bandwidth and device resources while also reducing update times for PCs on the same network. Delivery Optimization works by combining resources from all of your devices on the same network to accelerate the process of downloading and installing new packages.
It appears that you’re experiencing some uncontrollable fluctuations in internet bandwidth usage, or that you’re concerned about the security of your computer due to peer sharing running in the background.
