WDK for Windows 10, version 2004

download icon Step 1: Install Visual Studio 2019

The WDK requires Visual Studio. For more information about system requirements for Visual Studio, see Visual Studio 2019 System Requirements.

The following editions of Visual Studio 2019 support driver development for this release:

When you install Visual Studio 2019, select the Desktop development with C++ workload. The Windows 10 Software Development Kit (SDK) is automatically included, and is displayed in the right-hand Summary pane. Note that the version of the SDK that is compatible with the WDK for Windows 10, version 2004 may not be the default SDK. To select the correct SDK:

In Visual Studio Installer, on the Individual components tab, search for Windows 10 SDK (10.0.19041.0), select this version and continue with install.

If you already have Visual Studio 2019 installed, you can install the Windows 10 SDK (10.0.19041.1) by using the Modify button in Visual Studio install.

WDK has Spectre mitigation enabled by default but requires spectre mitigated libraries to be installed with Visual Stuido for each architecture you are developing for. Additionally, developing drivers for ARM/ARM64 require the build tools for these architectures to also be installed with Visual Studio. To locate these items you will need to know the latest version of MSVC installed on your system.

To find the latest version of MSVC installed on your system, in Visual Studio Installer go to workload page, on the right pane under installation details, expand Desktop development with C++ and locate the MSVC v142 - VS 2019 C++ x64/x86 build tools (V14.xx) - note where xx should be the highest version available.

With this information (v14.xx), go to Individual components and search for v14.xx. This will return the tool sets for all architectures, including Spectre mitigated libs. Select the driver architecture you are developing for.

For example, searching for v14.25 returns the following:

MSVC v142 - VS 2019 C++ ARM build tools (v14.25)
MSVC v142 - VS 2019 C++ ARM Spectre-mitigated libs (v14.25)
MSVC v142 - VS 2019 C++ ARM64 build tools (v14.25)
MSVC v142 - VS 2019 C++ ARM64 Spectre-mitigated libs (v14.25)
MSVC v142 - VS 2019 C++ x64/x86 build tools (v14.25)
MSVC v142 - VS 2019 C++ x64/x86 Spectre-mitigated libs (v14.25)

The WDK Visual Studio extension is included in the default WDK installation.

Enterprise WDK (EWDK) for Windows 10, version 2004

The EWDK is a standalone, self-contained command-line environment for building drivers. It includes the Visual Studio Build Tools, the SDK, and the WDK. The latest public version of the EWDK contains Visual Studio 2019 Build Tools 16.3.0 and MSVC toolset v14.23. To get started, mount the ISO and run LaunchBuildEnv.

The EWDK also requires the .NET Framework version 4.7.2. For more information about other requirements for the .NET Framework, see .NET Framework system requirements.
