Issue: How to Uninstall Bonjour?

I have a problem with Bonjour program on my PC. I’ve noticed random system crashes and checked the event viewer, which typically indicates Bonjour as the culprit. The truth is that this program is no longer in use as it was necessary for me when I was using iTunes and other Apple products. That’s why I’ve decided to remove it. The problem is that when I try to uninstall it via Control Panel, I receive a notification “The folder path ‘Program Files’ contains an invalid character,” which prevents the removal process. Could you please tell me what should I do?

Solved Answer

Bonjour (also known as zero-configuration networking) is often installed by default along with the Apple products, such as iTunes. Adobe software often comes in a bundle with Bonjour as well. It is an advantageous tool as it allows users to set up a network without any configuration. In other words, it detects all PCs, devices, and even file-sharing servers on the same IP network. Since Bonjour is often installed by default along with other software, people do not even know about it until, for example, they decide to optimize the system by deleting useless programs or when the system starts crashing due to the Bonjour service. It comes out that this software is automatically injected into the list of startup programs, meaning that it is launched by default when the system is booted and uses the CPU whether the PC owner is using the service or not. Usually, Bonjour-related process mDNSResponder.exe can easily be terminated via Task Manager, but it tends to restart automatically, which is a bit annoying. Additionally, many people have reported that they cannot find the uninstaller on the Control Panel and that’s the reason why it is often dubbed as a virus. Finally, even if the Bonjour uninstaller is placed on Add/Remove Programs, the removal is not permitted due to the mdnsNSP.dll folder or “The folder path ‘Program Files’ contains an invalid character” error message. Luckily, it’s not a deadlock and the solution is quite primitive. There are several methods that you can try to uninstall Bonjour on Windows permanently and we will list all of them below.
