Bonjour is a service created by Apple that is installed with iTunes and other Apple software products. It is a zero configuration networking utility that allows your computer to discover other computers, devices and services on your network. This can be useful for locating media files and streaming them over your network and for dynamically changing settings as required by the demands of applications that make use of Bonjour. If Bonjour is missing or damaged, you can reinstall it for free from the Apple website.
Click "Start" and type "Add or Remove Programs" in the Start menu search bar. Press "Enter."
Scroll down to "Bonjour" and click it.
Click "Uninstall" from the Add or Remove Programs toolbar.
Click "Remove," then press "Next."
Download the latest edition of Bonjour from the Apple.com website. A link has been included in the Resources section. Save it to your desktop.
Double-click the Bonjour set-up file and click "Next" at the welcome screen.
Review the license agreement and click "I accept the terms in the license agreement" to proceed.
Click "Finish" once installation has completed. You have now reinstalled Bonjour for Windows.
