Microsoft will use its customers' upload bandwidth to deliver Windows 10's updates and apps with a peer-to-peer technology resembling BitTorrent, a fact that has caught some by surprise.

Baked into Windows 10 is a new technology Microsoft dubbed "Windows Update Delivery Optimization" (WUDO) that is turned on by default for all editions of Windows 10. However, only some SKUs (stock-keeping units) -- notably Windows 10 Home and Windows 10 Pro -- are set to provide updates and apps to other devices when connected to the public Internet.

Windows 10 Enterprise and Windows 10 Education, volume-licensed SKUs for large companies and organizations, also have WUDO enabled, but default to sharing updates and apps only within a local network.

WUDO resembles BitTorrent in its basics, and like that file-sharing technology, uses a peer-to-peer delivery system to spread the load to PCs worldwide rather than relying on a centralized-servers model.

If WUDO is enabled, Microsoft can point others to locally-cached copies of updates and apps on users' Windows 10 devices that are connected to the Internet. When that happens, a user's Windows 10 PC acts as a substitute server for others, and any customer whose device is tapped for WUDO delivery has given Microsoft access to their upload bandwidth.

    Those are pretty great. Thanks for sharing.

    I'm still baffled at the amount of places they report home in an OS. I watched a few hours of the keynote earlier this year, so I knew that there would be the Cortana stuff, but wow, man. It's kind of out of hand.
