Installing iTunes for Windows
The install process of iTunes is straight-forward, but you need to know that following the default installation wizard of iTunes will make the iTunes player the default audio player for Windows, and it automatically updates the software when available or as per the set schedule.
Some users of iTunes only want the synchronization and conversion feature, which means they should uncheck the last 2 boxes below when installing iTunes for Windows: iTunes installation will add QuickTime Player, PictureViewer, Apple Software Update, Apple Application Support, Apple Mobile Device Support and Bonjour. You can safely remove Apple Software Update, Apple Mobile Device Support and Bonjour software using the Add or Remove Programs utility in Windows, if you don’t need the services or software.
Users of iTunes cannot remove QuickTime Player, as it is supposedly required for using the iTunes media player. Apple has integrated QuickTime, so you can use it to play media files online or offline.
Three Apple connected services will be added in Windows: Apple Mobile Device, Bonjour Service and iPod Service. The first two will be gone, if you have removed Apple Mobile Device Support and Bonjour software using the add or remove program utility.
There will be unnecessary startup items for Windows after installing iTunes: QTTask and iTunes Helper. You can stop these items from loading during the Windows startup by opening the System Configuration Utility (MSCONFIG) in Windows. You can also use CCleaner or WinPatrol to manage startup items in Windows.
