Microsoft releases monthly Windows updates to enhance security and functionality, but users often encounter issues like broken printers or malfunctioning software. Windows PCs may upload update files to other computers through a feature called Delivery Optimization, which aims to speed up the update process by allowing peer-to-peer sharing of files. While this can improve efficiency, many users prefer to disable it due to concerns about bandwidth and control over their hardware and internet connection. Disabling Delivery Optimization can be done through the Settings menu in Windows 11, allowing updates to be downloaded directly from Microsoft's servers. Users can also choose to share updates only with local devices or adjust the Background Intelligent Transfer Service (BITS) for better resource management.
