With the up coming Windows 10 1903 version you better be prepared, and save some bandwidth by setting up the right settings like Delivery Optimization.

What is Delivery Optimization ?

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

In many business networks, downloading apps and updates can be slow, inefficient, and, in many markets, expensive. When speaking with our customers, we often hear that they have regional facilities in limited and/or metered markets where devices download the same content, redundantly impacting coveted bandwidth and, ultimately, the organization’s financial bottom line. In almost any network, Delivery Optimization can be a highly effective tool, efficiently delivering content to devices and reducing the need for more internet bandwidth.

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.
