Fire up Software Update, because it’s time to tune up. Apple has squeezed out an iTunes point update that offers no new features, those came in the previous release, but there are bug fixes.

• Addresses issues with adding artwork to songs and videos
• Resolves an issue which may cause iTunes to become unresponsive when purchasing an HD movie
• Fixes a problem where iTunes may take longer than expected to open after waking your Mac from sleep
• Addresses issues with VoiceOver support
• iTunes 10.4.1 for Windows (64 bit) (Download) is available
