Bonjour, also known as zero-configuration networking, enables automatic discovery of computers, devices, and services on IP networks. Bonjour uses industry standard IP protocols to allow devices to automatically discover each other without the need to enter IP addresses or configure DNS servers.
If you’ve installed software such as iTunes by Apple, the chances are there’s already a Bonjour folder in your Program Files. This service starts automatically and runs a process named mDNSResponder.exe which cannot be killed by Windows Task Manager. If you do not want Bonjour to be on your computer and want to uninstall it, sometimes you can’t find any uninstaller for it! Even if you go to Control Panel’s Add or Remove Program, you can’t find the uninstaller there as well.
Here’s how to safely uninstall and remove the Bonjour service and files (mDNSResponder.exe and mdnsNSP.dll). Just follow the few simple steps below to remove Bonjour from your computer.
Warning: iTunes and some other programs need Bonjour to function. If you use these programs, do NOT remove Bonjour!
NOTE: Make sure you have administrator privileges before executing these commands. You might have to delete the quotes and input them manually, because WordPress.com is outputting them as smart quotes.
- Go to [Start > Run] and type the following command and hit OK.
- “%PROGRAMFILES%\Bonjour\mDNSResponder.exe” -remove
- Go to [Start > Run] again and type the following command and hit OK.
- regsvr32 /u “%PROGRAMFILES%\Bonjour\mdnsNSP.dll”
After you restart, you can safely delete the Bonjour folder without errors.
To know if you have actually uninstalled Bonjour. Open services.msc and see if there is a service similar to: “##Id_String2.6844F930_1628_4223_B5CC_5BB94B879762##”. If it is not there, then it has been uninstalled. But the folder and files remain in the program files folder. Just in case you want to install it again.
If you encountered problems after uninstalling or removing Bonjour, you can download and reinstall Bonjour. [Download Bonjour for Windows]
