Installing preview versions of the Windows Driver Kit (WDK)

  • Artykuł

This page contains installation instructions for Insider Preview (pre-release) versions of the Windows Driver Kit (WDK). The download links for the latest pre-release version of the WDK and the EWDK are on https://www.microsoft.com/software-download/windowsinsiderpreviewWDK.

Install Windows Driver Kit (WDK) Insider Preview

1. Install Visual Studio

  • The WDK now supports Visual Studio 2022. All editions are supported. The WDK no longer supports Visual Studio 2019.
  • Download from Visual Studio 2022.
  • Select workload: Development with C++.
  • For Arm64 and Arm64EC drivers, you must additionally install the component: Individual components -> Compilers, build tools, and runtimes -> Visual C++ compilers and libraries for Arm64/Arm64EC. Note that the WDK has Spectre mitigation enabled by default but requires Spectre mitigated libraries to be installed with Visual Studio for each architecture you are developing for.

2. Disable strong name validation

The WDK Visual Studio Extensions are currently not strong name signed. Run the following commands from an elevated command prompt to disable strong name validation:

reg add HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\StrongName\Verification\*,31bf3856ad364e35 /v TestPublicKey /t REG_SZ /d 00240000048000009400000006020000002400005253413100040000010001003f8c902c8fe7ac83af7401b14c1bd103973b26dfafb2b77eda478a2539b979b56ce47f36336741b4ec52bbc51fecd51ba23810cec47070f3e29a2261a2d1d08e4b2b4b457beaa91460055f78cc89f21cd028377af0cc5e6c04699b6856a1e49d5fad3ef16d3c3d6010f40df0a7d6cc2ee11744b5cfb42e0f19a52b8a29dc31b0 /f
