In this article, I will help you to understand what is Bonjour service and how to disable or deactivate it from running on your computer.

While searching through the task management for that irritating little process eating all your resources, a handful of you may have found a process marked as Bonjour Service. However, even fewer people understand what the service is and its role in their day-to-day PC activity.

First and foremost, the Bonjour Service is not a virus. It was created by Apple and has been a feature of their operating systems, iOS and macOS, since 2002. The app is extensively linked to the Apple ecosystem and contributes to a more seamless overall experience. On the other hand, the program gets onto a Windows computer when the user installs Apple-related software such as iTunes or the Safari web browser.

This article will go through the Bonjour Service and if you need it or if it can be removed from your Windows computer. If you choose the latter, I offer a step-by-step guide on disabling or removing the Bonjour service.


What is Bonjour Service on Windows 10?

Bonjour, formerly known as Apple Rendezvous, is a service that aids in the discovery and connection of shared devices and services across a local network. Unlike conventional apps, Bonjour runs in the background, allowing other Apple apps and programs to communicate across a local data network automatically. As a result, zero-configuration networking allows the user to set up a network without any configuration (zeroconf).

Modern technologies such as hostname resolution, address assignment, and service discovery enables this. At the same time, the usage of the multicast Domain Name System (mDNS) assures that the Bonjour Service does not impede internet speed by caching support information. Nowadays, the service mainly use for file sharing and printer discovery.
Among Bonjour’s apps are:

Shared music and photographs can be found in iTunes and iPhoto, respectively.

To locate local servers and device configuration pages in Safari.

For handling software licenses such as SolidWorks and PhotoView 360.

To locate contributors for a specific document in SubEthaEdit.

To communicate with many customers using software like iChat, Adobe Systems Creative Suite 3, etc.

The Bonjour service on Windows systems serves no purpose and can be disabled.

However, if you use Apple software (iTunes or Safari) on your Windows PC, Bonjour is an essential service, and uninstalling it may cause these apps to cease operating. Apple software and third-party apps such as Adobe Creative Suite and Dassault Systemes’ Solidworks require the Bonjour service to function correctly. So, before you deactivate Bonjour, make sure no need for any other app on your computer.

How to disable Bonjour service?

There are two methods for uninstalling the Bonjour service. You can either temporarily disable the service or completely uninstall it. Uninstalling the service is a permanent change, and if you later decide you need it, you will have to reinstall it, but in the other scenario, you can activate it again.

To disable a service on your computer, launch the Windows Services app. Set the launch type for the unwanted service to Disabled.
