Fix Windows SDK compilation errors with compiler settings

- Add Windows-specific compiler definitions (WIN32_LEAN_AND_MEAN, NOMINMAX, etc.)
- Set Windows version macros (_WIN32_WINNT, WINVER) for Windows 10 compatibility
- Add MSVC-specific compiler options (/permissive-, /Zc:__cplusplus, /utf-8)
- Use C++14 on Windows to avoid potential SDK conflicts with C++17 features

Addresses winnt.h syntax errors and Windows SDK header conflicts.
