What is Delivery Optimization?

Delivery Optimization is responsible for how updates are downloaded (and uploaded) on Windows. Instead of every computer downloading updates on its own, Delivery Optimization lets updates and apps be shared across multiple devices in your local network and even on the Internet.

This means if one PC in the network downloads an update, other PCs can get the update from it, instead of downloading all over again from Microsoft. This cuts down on the internet data used and makes updates faster to install.
