They are already written in C++, pay attention to the news! https://blogs.msdn.microsoft.com/vcblog/2014/06/10/the-great-c-runtime-crt-refactoring/ https://blogs.msdn.microsoft.com/vcblog/2014/06/10/the-great... "We have converted most of the CRT sources to compile as C++, enabling us to replace many ugly C idioms with simpler and more advanced C++ constructs. The publicly callable functions are still declared as C functions, of course (extern "C" in C++), so they can still be called from C. But internally we now take full advantage of the C++ language and its many useful features." Note the reference to ugly C idioms. Also all major C compilers are written in C++, including clang and gcc, did you miss that as well?

  Seeing "replace ugly C idioms" my first reaction was: "why didn't they use "nice C idioms instead?".

    Because nice C idioms is an oxymoron.

  CRT != ntdll.dll and CRT != kernel32.dll. CRT is an optional component of Windows software, a layer above ntdll and kernel32. Anyone can easily compile a program without C runtime library using /Zl compiler option. In this case, only Win32 and native API functions will be available, but not functions like printf() or strcmp(). So latest versions of CRT could be rewritten in C++, but this has nothing to do with documented OS API or even low-level undocumented native API, which are both still pure C.
