Microsoft's Delivery Optimization feature in Windows 11 enables PCs to share update files with others, potentially consuming user bandwidth without explicit consent. While designed to enhance update efficiency, many users find this practice intrusive. Reports indicate that some users experience significant upload speeds, raising concerns over privacy and resource management. To regain control, users can easily disable Delivery Optimization through the Windows settings by navigating to Windows Update, selecting Advanced Options, and turning off the feature. Alternatively, they can restrict sharing to devices on their local network. Additionally, the Background Intelligent Transfer Service (BITS) can be managed to limit background activity, although disabling it may impact other Microsoft services. Ultimately, users desire to ensure their PCs serve their personal needs rather than contribute to Microsoft's update distribution network.
