BITS
[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The Background Intelligent Transfer Service is a feature of the Windows operating system. BITS transfers files (downloads or uploads) between a client and server, and provides progress information related to the transfers. If you want to transfer files using C++ code, BITS is the correct technology to use. If you want to transfer files using JScript code in your online store webpage, use the Download Manager instead.
Because the Windows Media Player Download Manager uses BITS, you can take steps to configure your BITS copy jobs in such a way that Windows Media Player manages the jobs for you. To do this, you must follow the convention described in the Windows Media Player BITS Job Convention section when adding your jobs to the BITS transfer queue. This section also describes a mechanism for retrieving information about your BITS jobs from your online stores webpage.
