After seening the stuff like a Cydia hack that enables AirPlay in any third-party app, AirPlay support on Android and more. Developer Thomas Pleasance now enabled AirPlay on Windows Media Center devices.
Note: You must have Apple's Bonjour running on your Media Center PC prior to installing AirPlay for Windows Media Center add-in. Bonjour is included with Apple's free programs for Windows, such as iTunes, QuickTime, Safari and more.
"Upon installing the add-in on Mac mini running Windows 7, running the WMC app in Windows -- you'll able to stream media from an iPhone 4 to WMC by tapping the AirPlay icon in iOS media player and choosing "Windows Media Center" in the list of AirPlay-enabled devices. AirPlay is confined to Apple's iOS gadgets and Microsoft's Media Center is arguably among the best media center implementations on PCs and the Xbox 360 console so enabling media streaming between the two platforms makes perfect sense, in my personal opinion."
