Let me quote ITsVista:
"The Function Discovery Provider Host service allows resources to be discovered over the network. Function Discovery provides a uniform programmatic interface for enumerating system resources, such as hardware devices, whether they are local or connected through a network. Applications can use Function Discovery to discover which functions the computer can perform, regardless of the underlying device or software architecture. One of the more notable resources that depend on this is the Media Center Extender (an XBOX that can play media from your computer), but it can also be used to discover networked cameras, printers, disks, etc. If you are fine with manually setting these items up you may be able to get away with disabling this service, but since the default setting is ‘manual’, you probably won’t save any resources, so you might as well leave it alone."

So if you turn it off, the shared files are no longer visible by other computers in the network. Disabling this service is also possible by disabling the option Network discovery in the Network and Sharing Center in the Control Panel.
