Delivery Optimization is a peer-to-peer customer update service that uses both local and non-local PCs over the Internet. The goal is to deliver updated bits of Windows 10 to networked PCs in the organization. To do this, some of the data from local PCs and some of the data from Microsoft’s data centers are combined to get the full update. The main idea is to reduce bandwidth issues during the update and increase the speed of the update.

Despite this main goal, users have encountered many problems after implementing the update, such as high hard disk load or slow computer performance.
