Network device drivers for Windows XP use NDIS 5.x and may work with subsequent Windows operating systems, but for performance reasons network device drivers should implement NDIS 6.0 or higher. [8] Similarly, WDDM is the driver model for Windows Vista and up, which replaces XPDM used in graphics drivers.
USB 3.0 SuperSpeed – host controller (xHCI) hardware support, no software overhead for out-of-order commands; USB 2.0 High-speed – enables command queuing in USB 2.0 drives; Streams were added to the USB 3.0 SuperSpeed protocol for supporting UAS out-of-order completions USB 3.0 host controller (xHCI) provides hardware support for streams
The xHCI reduces the need for periodic device polling by allowing a USB 3.0 or later device to notify the host controller when it has data available to read, and moves the management of polling USB 2.0 and 1.1 devices that use interrupt transactions from the CPU-driven USB driver to the USB host controller.
Beginning with Windows XP Service Pack 1, generic USB 2.0 Enhanced Host Controller Interface drivers are installed. [69] Windows XP also adds support for USB device classes such as Bluetooth, USB video device class, imaging (still image capture device class) and Media Transfer Protocol with Windows Media Player 10.

Previously, the WDK was known as the Driver Development Kit (DDK) [4] and supported Windows Driver Model (WDM) development. It got its current name when Microsoft released Windows Vista and added the following previously separated tools to the kit: Installable File System Kit (IFS Kit), Driver Test Manager (DTM), though DTM was later renamed and removed from WDK again.
Windows Windows XP has a class driver for USB video class 1.0 devices since Service Pack 2, as does Windows Vista and Windows CE 6.0. A post-service pack 2 update that adds more capabilities is also available. [8] Windows 7 added UVC 1.1 support. Support for UVC 1.5 is currently only available in Windows 8, 10 and 11.
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 USB 3.1 specification takes over the existing USB 3.0's SuperSpeed USB transfer rate, now referred to as USB 3.1 Gen 1, and introduces a faster transfer rate called SuperSpeed USB 10 Gbps, corresponding to operation mode USB 3.1 Gen 2, [62] putting it on par with a single first-generation Thunderbolt channel.
