Windows Update Delivery Optimization

While troubleshooting a bandwidth issue for a customer today I noticed a lot of TCP traffic between different hosts of the customer on tcp port 7680. As the customer has multiple locations with diverse bandwidths available this started to hog up quite some bandwidth. After some research I found out that tcp port 7680 is used by Windows 10 to distribute windows updates to other domain clients.
