Download the Windows Driver Kit (WDK)

The WDK is used to develop, test, and deploy drivers for Windows. The most recent public release is WDK 10.0.22621.

  • You can install and run this WDK on Windows 7 and later.
  • You can use this kit to build drivers for Windows 10, Windows Server 2016 and later client and server versions.

To target Windows 8.1, Windows 8, and Windows 7, install an older WDK and an older version of Visual Studio either on the same machine or on a separate machine. For links to older kits, see Other WDK downloads.

Join the Windows Insider Program to get WDK Insider Preview builds. For installation instructions for the Windows Insider Preview builds, see Installing preview versions of the Windows Driver Kit (WDK).

The WDK requires Visual Studio. For more information about system requirements for Visual Studio, see Visual Studio 2022 System Requirements.

The following editions of Visual Studio 2022 support driver development for this release:

When you install Visual Studio 2022, select the Desktop development with C++ workload, then under Individual Components add:

  • MSVC v143 - VS 2022 C++ ARM64/ARM64EC Spectre-mitigated libs (Latest)
  • MSVC v143 - VS 2022 C++ x64/x86 Spectre-mitigated libs (Latest)
  • C++ ATL for latest v143 build tools with Spectre Mitigations (ARM64/ARM64EC)
  • C++ ATL for latest v143 build tools with Spectre Mitigations (x86 & x64)
  • C++ MFC for latest v143 build tools with Spectre Mitigations (ARM64/ARM64EC)
  • C++ MFC for latest v143 build tools with Spectre Mitigations (x86 & x64)

Hint: Use the Search box to look for "64 latest spectre" to quickly see these components.

Note: The Desktop development with C++ workload selected above also installs the Windows SDK 10.0.22621.

Installing Visual Studio should automatically download the Windows SDK 10.0.22621. In the event that it does not, use the following link:

The provided links for the SDK and the WDK have matching build numbers, which is always required for the kits to work together. If you decide to install your own SDK/WDK pair, perhaps for a different Windows version, ensure that the build numbers match. For more details, see Kit versioning.

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

Tip

If you can't find driver project templates in Visual Studio, the WDK Visual Studio extension didn't install properly. To resolve this, run the WDK.vsix file from this location: C:\Program Files (x86)\Windows Kits\10\Vsix\VS2022\10.0.22621.2428\WDK.vsix.

As an alternative to downloading Visual Studio, the SDK, and the WDK, you can download the EWDK, which is a standalone, self-contained command-line environment for building drivers. It includes Visual Studio Build Tools, the SDK, and the WDK.

The latest public version of the EWDK contains Visual Studio 2022 Build Tools 17.1.5 and MSVC toolset v14.31.

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.

Once you have downloaded the ISO, use these steps to set up your build environment:

  1. Mount the EWDK ISO from a drive volume. Network share paths aren't currently supported.
  2. Run LaunchBuildEnv.cmd.
  3. In the environment created in step 2, type SetupVSEnv, and then press Enter.
  4. Launch devenv.exe from the same environment, using the full file path. For example: "C:\Program Files\Microsoft Visual Studio\2022\%Community|Professional|Enterprise%\Common7\IDE\devenv.exe"
  5. When you're done with the build environment, you may want to eject the ISO.

You can optionally use the Visual Studio interface with the build tools provided in the EWDK. To do this, ensure that the Visual Studio major version matches the version of the Visual Studio Build Tools in the EWDK. For example, Visual Studio 2022 works with the EWDK that contain VS17.X build tools. For a list of Visual Studio 2022 version numbers, see Visual Studio 2022 Releases.

Kit versioning

A full kit build string includes as its last two components, the build number and a QFE (Quick Fix Engineering) value. For example, 10.0.22621.2428 has a build number of 22621, and a QFE value of 2428.

To build a driver, the build number of your SDK installation must match the build number of your WDK installation. The QFE values does not need to match unless your driver uses functionality that is only available in the headers included with a later QFE.

A quick way to see the full build string for locally installed kits is to go to Windows settings (Win+I), navigate to Apps, then Installed apps, and in the Search box type kit. The full build string appears to the right of the kit name. If you navigate to C:\Program Files (x86)\Windows Kits\10\Include, note that the QFE shown there is hardcoded to .0, so this is not a reliable way to check your QFE identifier. Also note that when you install a kit, the new installation replaces any previously existing installation of the same build number. When you install Visual Studio with the Desktop development with C++ workload, if the installation payload includes the Windows SDK, the right-hand Summary pane also shows a hardcoded .0 for QFE.
