Do You Really Need Bonjour? How to Uninstall iTunes Bonjour

imyfone app

Bonjour is a utility program that is integrated into some Apple programs. It is usually used by iTunes to find shared music libraries, AirPort Express devices for streaming music to and to find Apple TVs. Safari also uses Bonjour to find devices advertising web pages on your network.

It is usually installed automatically when you install iTunes and it runs a process that starts up and runs in the background when you start your system. All of this is done in the background and, a lot of the time, you don’t really know that it’s there.

Can I Uninstall Bonjour and Still Use iTunes Normally?

If you ordinarily use any of the services provided by Bonjour, then the apps through which you use those features need Bonjour to work. Removing Bonjour from your device will cause those apps to stop working properly.

But if you don’t do anything of Home Sharing, remote app or syncing to Apple TVs, you can uninstall bonjour. iTunes will remind you once next time you open it and that will be that. It will work fine.

Besides, you can also uninstall Apple Software Update if you don’t want that running. But don’t uninstall Apple Application Support because they are absolutely needed for iTunes to function.

How to Manually Uninstall Bonjour iTunes

If you have any Apple software on your device, there’s a high probability that you have a Bonjour folder in your program files. It starts up automatically and runs a process named mDNSResponder.exe. This process cannot be stopped by Windows’ task manager. So if you want to get rid of it, you have to remove Bonjour.

Way 1: Uninstall Bonjour from Control Panel

Generally, you can remove Bonjour from your Control Panel. You can ordinarily do this by going to Control Panel and clicking “Programs and Features”. Find the program called “Bonjour” and right click on it to choose “Uninstall”. However, this process may fail to completely remove Bonjour from your device and it may cause operating problems for your iTunes.

Way 2: Remove Bonjour Service and Files

Another method you can use to remove Bonjour from your device as well as its files – mDNSResponder.exe and mdnsNSP.dll – is as follows.

Step 1: On your PC, go to C:\Program Files\Bonjour.

Step 2: Find the "mDNSResponder.exe" file. Right-click on it and choose "Delete".

Step 3: Find the "mdnsNSP.dll" file. Right click on it and choose "Delete".
Note: If you receive a notification "This action can't be completed because the file is open in Bonjour service", restart your computer and try to delete them again.

Step 4: Once done, restart your computer, go to “C:\Program Files\” and delete the Bonjour folder.

This process allows you to fully remove Bonjour from your device. However, it obviously takes time and more than a little bit of knowhow. There’s a better and safer way to remove Bonjour from your device in an even safer, quicker manner.
