Windows Update Delivery Optimization enables you to download Windows updates and Windows Store apps from sources other than Microsoft. This can help you get updates and apps more quickly if you have a limited or unreliable Internet connection. If you own more than one PC, Delivery Optimization can reduce the amount of Internet bandwidth that is required to keep all your PCs up-to-date. Delivery Optimization also sends updates and apps from your PC to other PCs on your local network or on the Internet.
