Hey guys, For the past month or so I have been having problems with my computer freezing when trying to exit iTunes, but I finally figured it out. Go To Start, Right click on My Computer and Go to Manage. Then, click on services and applications, then services, and right click on Bonjour Service and go to properties In the General tab, go to startup type and select Manual or Disabled. And there you go... iTunes does not freeze anymore when you try to close it. Hope this helps.
