[Service Name] Distributed Link Tracking Client [Recommended Setting] Disable [Notes] 
Maintains links with NTFS files within your computer or across a domain. I don't think many people would have a use for this unless you are on a corporate network. What Microsoft has to say: "The distributed link-tracking service enables client applications to track link sources that have been moved. Clients that subscribe to the link-tracking service can maintain the integrity of their references, and the objects can be tracked in a manner that is transparent to the user."
