Windows 10's new beta lets computers download updates from other PCs

Microsoft is trying to make it faster for people to download Windows updates by using the vast network of PCs around the world to deliver them.

A new beta build of Windows 10 released on Wednesday enables Delivery Optimization by default, which lets PCs download update bits from other computers connected to the internet. Those bits can be delivered alongside those brought in from Microsoft's servers, to help speed up the process of downloading updates, especially on less reliable network connections.

The feature works similarly to the BitTorrent file distribution system. Update files get split into chunks, and then Windows 10 will download each chunk from the device that can deliver it the fastest. Microsoft first introduced the feature with the major Windows 10 update last November, but it only allowed people to download updates from computers on a local network or from Microsoft's servers.

Users who want to turn off Delivery Optimization can go to Settings > Update & Security > Windows Update > Advanced options and then click on "Choose how updates are delivered." Once there, they can disable their computer's ability to download updates from multiple computers, or just limit it to download only from other devices on its local network.

IT administrators will be able to control these settings through Group Policies or device management software. It's also possible for administrators to expand the definition of their company's local network beyond the LAN in a single building, allowing computers in one office to download update bits from those in another office.
