How to Enable or Disable Windows Update Delivery Optimization
Windows Update Delivery Optimization is a feature that lets your PC share update files with other computers, speeding up downloads.
This peer-to-peer technology allows your Windows 10 or Windows 11 device to download update pieces from nearby PCs and the internet, and in turn, upload those pieces to other devices. It’s designed to reduce bandwidth usage and download times, especially when you have multiple Windows machines.
By default, Delivery Optimization is often enabled in Windows, and it works in the background. You can choose to disable it if you prefer your PC to only download updates directly from Microsoft’s official servers, giving you full control over your internet traffic.
Enable or disable Windows Update Delivery Optimization by going to Settings, then Windows Update, Advanced options, and toggling “Allow downloads from other PCs” on or off. This setting controls whether your PC shares update files with other devices on your network or the internet.
