Windows Media

Windows Media is a discontinued multimedia framework for media creation and distribution for Microsoft Windows. It consists of a software development kit (SDK) with several application programming interfaces (API) and a number of prebuilt technologies, and is the replacement of NetShow technologies.

The Windows Media SDK was replaced by Media Foundation when Windows Vista was released.
