How To Remove or Uninstall Bonjour Service (mDNSResponder.exe)
Posted by Alex on Thursday, July 16, 2009Bonjour, also known as zero-configuration networking , enables automatic discovery of computers, devices, and services on IP networks.
If you’ve installed software by Apple such as iTunes, Premiere Pro, Skype, Gizmo, 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 ended by Windows Task Manager. If you don't want Bonjour to be in 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.
Fortunately, Here’s a trick to safely uninstall Bonjour and remove mDNSResponder.exe
Just follow the instruction below to remove Bonjour from your computer manually.
Step 1: Go to Start > Run > type the command below and hit OK.
“%PROGRAMFILES%\Bonjour\mDNSResponder.exe” -remove
Step 2: Navigate to C:\Program Files\Bonjour
Step 3: Rename the mdnsNSP.dll file in that folder to mdnsNSP.old
Step 4: Restart your computer
Step 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 it’s not there, you’ve successfully removed it.
Gizmo Project has created a small tool called TurnOffBonjour 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 you’re advised to delete the folder after restart is in case there’s a problem, the Bonjour files are still there for you to restore.
