  • We've made some important changes to the C/C++ ETW code generation of mc.exe (Message Compiler):
  • The "-mof" parameter is deprecated. This parameter instructs MC.exe to generate ETW code that is compatible with Windows XP and earlier. Support for the "-mof" parameter will be removed in a future version of mc.exe.
  • As long as the "-mof" parameter is not used, the generated C/C++ header is now compatible with both kernel-mode and user-mode, regardless of whether "-km" or "-um" was specified on the command line. The header will use the ETW_KM macro to automatically determine whether it is being compiled for kernel-mode or user-mode and will call the appropriate ETW APIs for each mode.

Preview SDK 17682 is now available to download from Microsoft. For the full list of API changes and details on what's new, you can check out Microsoft's full release notes.
