What is Bonjour?

Apple Inc.’s Bonjour software (initially named as ‘Rendezvous’) is an automatic network discovery technology and an implementation of zero-configuration networking (zeroconf).

Zeroconf is a group of technologies that includes service discovery, hostname resolution, and address assignment.

So, Bonjour can locate devices including printers, other computers or work stations, and the services that those devices extend on a local network automatically.

It does so by using multicast Domain Name System (mDNS) service records.

The setting up of network printers and file sharing through the utility saves time and also simplifies tasks. And, the technology is based on Internet Protocol (IP), which allows it to function both on wired as well as wireless networks.

Apple’s macOS and iOS operating systems have this built-in software, and the software can be also installed on Microsoft Windows.

The features and components of Bonjour are used by iTunes and some other programs towards sharing music libraries, connecting to AirPort Express devices, and functioning with Apple TVs.

The Bonjour software is said to also blend well with the Safari Web browsers to find out webpage-based interfaces for devices that are networked.

Bonjour Service in Windows 10

So, you are not using any of Bonjour’s features, and you wish to remove the software from Microsoft Windows? Here is a step-by-step process to thoroughly remove Bonjour.

First, look out for a Bonjour folder located under the ‘Program Files’ section.

You may try to uninstall the utility through the Control Panel (which may not succeed in some cases).

A surer method to uninstall and remove the Bonjour service and files including mDNSResponder.exe and mdnsNSP.dll is to try the following.

"%PROGRAMFILES%\Bonjour\mDNSResponder.exe" -remove
