Maintains an updated list of computers on the network and supplies this list to computers designated as browsers. Note: In Windows 8.1 and Windows 10, this service is bundled with the SMB 1.0/CIFS File Sharing Support optional feature. As a result, removing that feature (highly recommended unless backward compatibility is needed to XP/2003 and older Windows OSes - see Stop using SMB1 | Storage at Microsoft) will also remediate this recommendation. The feature is not installed by default starting with Windows 10 R1709. Default: Not Installed (Manual (Trigger Start) when installed) Counter Measure: The recommended state for this setting is Disabled or Not Installed.
