Airport Express not available anymore after upgrade to iTunes 12.1
I have Windows 7 Home Premium Service Pack 1 installed and did an iTunes upgrade from previous version to 12.1 . After the installation and restart I got the info that the 'Bonjour' service was stopped and I have to reactivate it again in the system settings. Having that done I still can't address the Airport Express speakers out of iTunes.
Any idea what I can do?
