iTunes 7.x for Windows XP and Vista installs some processes that run in the background when iTunes is not open. Here is a brief explanation of what each process does:

iPodService.exe Allows iTunes to access devices.
iTunes Helper.exe "Listens" for commands to help iTunes communicate with devices (such as iPod).
qttask.exe Provides a QuickTime icon in the Notification area (system tray) of the Windows Task bar. This process might or might not appear depending on your configuration of QuickTime and whether the QuickTime icon is enabled in the Notification area.
mDNSResponder.exe Allows iTunes to discover services on the local network (music sharing, Apple TV, AirTunes). Also known as Bonjour for Windows.
AppleMobileDeviceService.exe Allows iTunes to recognize iPhone and iPod touch
distnoted.exe Allows iTunes to sync with iPhone and iPod touch

Note: Depending on your configuration, some of these background processes may not appear. iTunes can start other background processes to perform various tasks like syncing and diagnostics. Apple may add new functions to these background processes in the future. Please note that you should not disable these processes even with iTunes not open on the computer.
