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. In which case do not remove!
NOTE: Make sure you have administrator privileges before executing these commands. (You might have to delete the quotes and input them manually)
Go to [Start > Run] and type the following command and hit OK.
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.
