What is Bonjour Service on Windows 10?
A few of you, while going through the task manager to find that pesky little process hogging up your resources, might have noticed a process listed as Bonjour Service. Although, even fewer know what the service really is and what role it plays in their day-to-day PC activities.
First up, the Bonjour Service is not a virus. It is an Apple-developed software and has been a part of their operating systems, iOS and macOS, since 2002. The application is deeply integrated within the Apple ecosystem and helps in making the overall experience more seamless. On the other hand, the software finds its way onto a Windows computer when the user installs an Apple associated software such as iTunes or Safari web browser.
In this article, we will be discussing in-depth about the Bonjour Service and whether you need it or if it can be purged from your Windows computer. If you decide on the latter, we have a step-by-step guide on how to disable the Bonjour service or get rid of it completely.
What is Bonjour Service on Windows 10?
Originally called Apple Rendezvous, Bonjour service helps discover and connect shared devices & services across a local network. Unlike regular applications, Bonjour works in the background while other Apple applications and programs use it to communicate over a local data network automatically. Therefore, allowing the user to set up a network without any configuration, also known as, zero-configuration networking (zeroconf).
This is made possible by the use of modern technologies such as hostname resolution, address assignment, and service discovery. While the use of multicast Domain Name System (mDNS) ensures the Bonjour Service doesn’t inversely affect your internet speed by caching support information.
Nowadays, the service is most commonly used for file-sharing and to discover printers. Some of Bonjour’s applications include:
- Find shared music and photos in iTunes and iPhoto respectively.
- To find local servers and configuration pages for devices in Safari.
- For managing licenses in software like SolidWorks and PhotoView 360.
- In SubEthaEdit to find collaborators for a certain document.
- To communicate with multiple clients in applications such as iChat, Adobe Systems Creative Suite 3, etc.
On Windows computers, the Bonjour service doesn’t have any direct function and can be removed.
Although, if you use an Apple software ( iTunes or Safari ) on your Windows PC, Bonjour is an essential service, and removing it may cause these applications to stop working. Not just Apple software, certain third-party applications like Adobe Creative Suite and Dassault Systemes’ Solidworks also need the Bonjour service to function properly. So before you move ahead and decide to remove Bonjour, ensure that it isn’t required by any application on your computer.
