Sets DoSvc (Delivery Optimization) to Manual instead of Automatic. DoSvc runs a peer-to-peer cache that shares Windows Update / Store content with other PCs on your network and the internet, holding RAM and using upload bandwidth in the background. Manual keeps Windows Update fully working (the service starts on demand for downloads) while removing the always-on idle footprint. Reversible.
MaxTweaks applies this tweak with one click and snapshots your original setting first, so you can revert it cleanly at any time. A System Restore point is offered before batch changes, and every tweak links to its official source.
