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 youíve installed software by Apple such as iTunes, software by Adobe such as Premiere Pro, Skype, Gizmo, chances are thereís already a Bonjour folder in your Program Files. This service starts automatically and runs a process named mDNSResponder.exe which cannot be ended by Windows Task Manager. If you do not want Bonjour to be in your computer and want to uninstall it, sometimes you canít find any uninstaller for it! Even if you go to Control Panelís Add or Remove Program, you canít find the uninstaller there as well.
Hereís how to safely uninstall Bonjour and remove mDNSResponder.exe
Just follow the few simple steps below to remove Bonjour fro your computer.
1. Go to Start > Run > type the command below and hit OK.
2. Navigate to C:\Program Files\Bonjour 3. Rename the mdnsNSP.dll file in that folder to mdnsNSP.old 4. Restart your computer 5. Delete the Program Files\Bonjour folder
The first command will stop and remove Bonjour Service from your computer. To confirm, go to Start > Run and type services.msc. Look for Bonjour Service name. If itís not there, youíve successfully removed it.
Gizmo Project has created a small tool (35KB TurnOffBonjour.exe)http://download.gizmoproject.com/jasmine/TurnOffBonjour.exe that turns off and removes Bonjour service. However, it will not remove the Bonjour folder from Program Files. You will still need to manually delete the Bonjour folder after restart. The reason why youíre advised to delete the folder after restart is in case thereís a problem, the Bonjour files are still there for you to restore.
