Windows Media Player

Windows Media Player (abbreviated WMP) is a proprietary digital media player and media library application developed by Microsoft that is used for playing audio, video and viewing images on personal computers running the Microsoft Windows operating system, as well as on Pocket PC and Windows Mobile-based devices. Editions of Windows Media Player were also released for Mac OS, Mac OS X and Solaris but development of these has since been discontinued.

Winrar

WinRAR is a popular shareware file archiver and data compression utility developed by Eugene Roshal, and first released in the fall of 1993. It is one of the few applications that is able to create RAR archives natively, because the encoding method is held to be proprietary.
