-# Windows-driver-samples
-This repo contains driver samples prepared for use with Microsoft Visual Studio and the Windows Driver Kit (WDK). It contains both universal driver and desktop-only driver samples. 
+# Driver samples for Windows 10 #
+These are the official Microsoft Windows Driver Kit (WDK) team driver code samples for Windows 10. They provide a foundation for universal driver support of all hardware form factors, from phones to desktop PCs. Use these samples with Microsoft Visual Studio 2015 CTP 6, Microsoft Visual Studio Tools for Windows 10 Technical Preview, Windows SDK for Windows 10, and WDK 10.
+
+## Windows 10 driver development ##
+Use Visual Studio 2015 CTP 6 and the the Windows 10 Driver Kit (WDK) to build, test, and deploy your drivers. With Windows 10, the driver development environment is integrated into Visual Studio. To get Windows 10 Technical Preview and the driver development kits and tools, join the Windows Insider Program.

+### Samples ###
+Use the samples in this repo to guide your Windows driver development. Whether you’re just getting started or porting an older driver to the newest version of Windows, code samples are valuable guides on how to write drivers.
+
+### Build your first driver ###
+If you're writing your first driver, use these exercises to get started. Each exercise is independent of the others, so you can do them in any order.

+AVStream simulated hardware sample driver (Avshws)
+==================================================
+
+The AVStream simulated hardware sample driver (Avshws) provides a pin-centric [AVStream](http://msdn.microsoft.com/en-us/library/windows/hardware/ff554240) capture driver for a simulated piece of hardware. This streaming media driver performs video captures at 320 x 240 pixels in either RGB24 or YUV422 format using direct memory access (DMA) into capture buffers. The purpose of the sample is to demonstrate how to write a pin-centric AVStream minidriver. The sample also shows how to implement DMA by using the related functionality provided by the AVStream class driver.
+
+This sample features enhanced parameter validation and overflow detection.
+
+## Universal Compliant
+This sample builds a Windows Universal driver. It uses only APIs and DDIs that are included in Windows Core.
