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.

Prevent websites, ISP, and other parties from tracking you

Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.

A VPN is also crucial when it comes to user privacy. Online trackers such as cookies can not only be used by social media platforms and other websites but also your Internet Service Provider and the government. Even if you apply the most secure settings via your web browser, you can still be tracked via apps that you are connected to the internet. Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speed.

Therefore, to stay completely anonymous and prevent the ISP and the government from spying on you, you should employ Private Internet Access VPN. It will allow you to connect to the internet while being completely anonymous, prevent trackers, ads, as well as malicious content. Most importantly, you will prevent the illegal surveillance activities that NSA and other governmental institutions are performing behind your back.


Recover your lost files quickly

Unforeseen circumstances can happen at any time while using the computer: it can turn off due to a power cut, a Blue Screen of Death (BSoD) can occur, or random Windows updates can decide to reboot the machine when you went away for a few minutes. As a result, your schoolwork, important documents, and other data might be lost.

Additionally, you might also be attacked by malware that can corrupt your Windows or encrypt files with a robust encryption algorithm, and ask for a ransom in Bitcoin for the decryption tool. Cybercriminals might not deliver what they promised, however, so it is better to attempt alternative file recovery methods that could help you to retrieve at least some portion of the lost data.

Data recovery software is one of the options that could help you recover your files. Once you delete a file, it does not vanish into thin air – it remains on your system as long as no new data is written on top of it. Data Recovery Pro is recovery software that searchers for working copies of deleted files within your hard drive. By using the tool, you can prevent loss of valuable documents, school work, personal pictures, and other crucial files.
