Windows 10 includes a new feature called Windows Update Delivery Optimization that can download updates from other PCs instead of directly from Microsoft servers. This can be beneficial if you have multiple Windows 10 computers on your local network because it reduces the amount of data transfer on your Internet connection. After a Windows 10 PC downloads an update, it can share the update with other computers in your home instead of downloading additional copies over the Internet. This is an awesome new feature that can help users save bandwidth, especially those on metered or slow internet connections. But there is one aspect of this feature I wish Microsoft disabled by default.
