Turn On or Off Windows Update Delivery Optimization in Windows 11 (2025)

This tutorial will show you how to turn on or off allow downloads from other PCs for Delivery Optimization in Windows 11.

Windows Update Delivery Optimization helps you get Windows updates and Microsoft Store apps more quickly and reliably.

Windows Update Delivery Optimization works by letting you get Windows updates and Microsoft Store apps from sources in addition to Microsoft, like other PCs on your local network, or PCs on the internet that are downloading the same files. Delivery Optimization also sends updates and apps from your PC to other PCs on your local network or PCs on the internet, based on your settings. Sharing this data between PCs helps reduce the internet bandwidth that’s needed to keep more than one device up to date or can make downloads more successful if you have a limited or unreliable Internet connection.

When Windows downloads an update or app using Delivery Optimization, it will look for other PCs on your local network (or from the internet, depending on your settings) that have already downloaded that update or app. Windows doesn’t download the entire file from one place. Instead, the download is broken down into smaller parts. Windows then gets parts of the update or app from the PCs that have it, and parts from Microsoft. Windows uses the fastest, most reliable download source for each part.

Delivery Optimization creates a local cache, and stores files that it has downloaded in that cache for a short period of time.

Delivery Optimization can’t be used to download or send personal content. Delivery Optimization doesn’t access your personal files or folders, and it doesn’t change any files on your PC.

Delivery Optimization downloads the same updates and apps that you would get through Windows Update and Microsoft Store, using the same security measures. To make sure you’re getting authentic updates, Delivery Optimization gets information securely from Microsoft to check the authenticity of each part of an update or app that it downloads from other PCs. The authenticity of the downloads is checked again before installing it.
