A header-only C++ library from Microsoft providing readable, type-safe C++ interfaces for common Windows coding patterns. It includes RAII resource wrappers, Win32 API helpers, registry helpers, network helpers, error-handling macros, and TraceLogging telemetry support.

Use cases

• manage Windows HANDLEs and resources with RAII smart pointers
• check Windows API errors and surface them as error codes or exceptions
• read and write the Windows registry in a type-safe way
• watch for Windows registry changes and trigger callbacks
• simplify Winsock and sockaddr handling in C++
• log telemetry with TraceLogging from C++

When to choose

• you are writing modern C++ that calls Win32 APIs and want RAII and type safety
• you want consistent error handling across the many Windows error-reporting conventions
• you need registry, networking, or telemetry helpers without writing boilerplate

When to avoid

• you are targeting non-Windows platforms
• your project is pure C or does not use C++
• you want a large framework rather than lightweight header-only helpers
