Turn Off Windows 10 Peer-to-Peer Delivery Optimization

Peer-to-peer downloading is pretty amazing technology. It can speed up downloads significantly, and it can make downloading significantly more resilient to network hiccups and other types of failures.

It’s most commonly associated with BitTorrent, which uses peer-to-peer to create a network of download sites that are efficient, resilient, and potentially difficult to track down. But the technology is used in other places as well – download a Linux distribution, and peer-to-peer BitTorrent downloads are often an option;¬†updates for large applications, like online games, are often provided using peer-to-peer technology.

Microsoft: Windows Update Delivery Optimization: FAQ

1: Actually, it’s significantly more complex than that. In true peer-to-peer file sharing, files are broken into pieces, and your machine could already be sharing the pieces it has while it downloads the rest of the pieces it needs from multiple other computers that already have those pieces, all at the same time. Complex, and, to a geek, very cool stuff.
2: I actually can’t think of a way to do it with great accuracy, and the cost of failure is high to the user.
3: The biggest complaint I hear is not that Microsoft is doing it, but that they do it by default, and without asking.
4: That’s a best-case scenario. In reality, I expect there to be some benefit, but nothing absolute.
