It is a replacement for the previous Windows 2000 and Windows XP display driver model XDDM/XPDM [3] and is aimed at enabling better performance graphics and new graphics functionality and stability. [2] Display drivers in Windows Vista and Windows 7 can choose to either adhere to WDDM or to XDDM. [4]
The transmit feature is built-in from launch for all Miracast devices with no additional setup past using the WIN+K keystroke to pair with a compatible display sink (including Microsoft's own Wireless Display Adapter). Developers can also implement Miracast on top of the built-in Wi-Fi Direct support in Windows 7 and Windows 8. [29]
Wireless Hosted Network capabilities: The Windows 7 wireless LAN service supports two new functions – Virtual Wi-Fi, that allows a single wireless network adapter to act like two client devices, [103] or a software-based wireless access point (SoftAP) to act as both a wireless hotspot in infrastructure mode and a wireless client at the same ...
