iTunes and Bonjour
I just noticed that I am no longer able to access sharing features in iTunes (12.11.0.26, current at the time of writing), running on Windows 10 (current at the time of writing).
The sharing tab in iTunes says "the Bonjour service has been disabled. Bonjour is required to share music with others. Please re-enable the service to use this feature."
I found, downloaded, and ran the Bonjour64 installer. Continued to get the same message in the iTunes sharing tab. I uninstalled Bonjour, rebooted, installed it fresh, rebooted and am getting the same message. Any ideas?
