If you happen to install iTunes, you will find that installs Bonjour Windows Service, a Zero Configuration Networking process and mDNSResponder.exe. Often iTunes is bundled along with other software and installed on the user’s computer, without the user’s knowledge. If you don’t use Bonjour or any of its features, then removing Bonjour shouldn’t cause any issue however, in some cases it is known to cause so. Here are the steps you can follow for more thoroughly uninstalling Bonjour.

Remove Bonjour from Windows

Firstly, if you have any Apple software installed on your computer such as iTunes there’s a high likelihood that there’s already a Bonjour folder residing under ‘Program Files’ section. On most occasions, the service starts automatically and runs a process named mDNSResponder.exe which cannot be killed by Windows Task Manager.

You will, in most cases, be able to uninstall the program via Control Panel – but in some cases, this may fail! Hence, a safe method described here to uninstall and remove the Bonjour service and files – mDNSResponder.exe and mdnsNSP.dll.

Press Win + R keyboard keys in combination, to bring up the ‘Run’ dialog box. Next, type the following command and hit OK. Alternatively open an elevated CMD and do it.

"%PROGRAMFILES%\Bonjour\mDNSResponder.exe" -remove

To unregister the dll file, open a command prompt window, as an administrator, type the following and hit Enter.

regsvr32 /u "%PROGRAMFILES%\Bonjour\mdnsNSP.dll"

Restart your computer, go to C:\Program Files\ and delete the Bonjour folder.

iTunes and some other programs need Bonjour to function. If you use these programs, do NOT remove Bonjour! Make sure you have administrator privileges before executing these commands.
