Sets WMPNetworkSvc (Windows Media Player Network Sharing Service) to Disabled and stops it. It streams Windows Media Player libraries to other devices/DLNA players on the network. If you don't share a media library over the LAN it runs for nothing. Local Windows Media Player playback is unaffected. Fully reversible (revert restores the original start type).
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.
