Windows 10 us es peer-to-peer technology to deliver Windows updates. This means your Internet connection is used to share the updates you’ve downloaded with other users. If you’re on a slow broadband connection – or you’d rather not let Microsoft do this – you can change it. Click ‘Start’ and choose Settings. Select ‘ Update & security’, and click ‘Advanced options’ under Windows Update. Next, click ‘ Choose how updates are delivered’, and either switch the feature off or select ‘ PCs on my local network’ to further cut bandwidth usage by only sharing the updates between the PCs you have in your home.
