peer-to-peer downloading

Peer-to-peer downloading in Windows is primarily used through Delivery Optimization, a feature that speeds up system updates and app downloads by sharing data between local devices on the same network or the internet. This approach reduces bandwidth usage and improves download reliability for Windows updates and Microsoft Store content. Users can configure Delivery Optimization settings to limit peer-to-peer activity to local network only or allow internet-based sharing, with options to control bandwidth usage. The feature is built into Windows 10 and 11, offering a secure and efficient way to manage large downloads while minimizing impact on network performance.
