ITunes

iTunes is Apple's music and video management software. It also serves as a desktop client for the iTunes Store and handles iOS device synchronization.

It consists of two major components: iTunes itself, and Apple Mobile Device Support (AMDS). Apple Mobile Device Support is the component responsible for synchronizing with iOS devices. Previous versions included QuickTime, which was used for media playback.

Starting with version 9, iTunes on Windows includes a component called Apple Application Support, which is essentially WebKit. It is used to display the iTunes Store, as well as iTunes LPs and iTunes Extras.

Version History
Note: Only versions 7.3.0 and newer are included; anything before did not contain support for the (then non-existent) iPhone.

Older video cards
Starting with iTunes 12.1, Apple made a version available for 64-bit Windows computers with older video cards.
