I had been running Windows Vista as my operating system. From last few weeks i had been noticing that my iTunes installs a Bonjour service at the startup. Just few days back i had installed new iTunes 5.0 version and whenever i try to turn on my system it automatically blocked a request from Bonjour service to jump on the net. So, can any body tell me that why does iTunes 5.0 loads Bonjour Service on my system? What i need to do to resolve the above issue? Does any body have any idea about it? kindly help me out to resolve the above issue. Thanks.
