Apple has released yet more software for Windows – a software development kit (SDK) for those building software on that platform that lets them integrate iTunes into third-party Windows applications.

ArsTechnica reports the release – which is available to members of the Apple Developer Connection – "exposes some iTunes functionality through the Windows Components Object Model interface". It means Windows developers can create code to allow their apps to control functions within iTunes.

The Web site reports that developers may be able to use the SDK to play AAC files – even those acquired from Apple's iTunes Music Store – using Windows applications such as WinAMP (once the requisite plug-ins are written).

The move could help "make FairPlay AACs the music digital rights management standard for both Mac OS X and Windows XP", the report speculates.
