I am really fed up with your constant updates to iTunes and QuickTime. Will you ever get them right or are your programmers so clumsy you need to issue a fix every two weeks ? And do you really need me to download 75Mb just for one fix ? Do we really need to reboot each time after installing a QuickTime or iTunes  update ?
Please stop trying to behave like the folks in Redmond. It does not serve your image.
