Support for Winsock tracing using ETW was added on Windows Vista and later.

ETW was first introduced on Windows 2000. This allows large-scale server applications to write events with minimum disturbance. The logging mechanism uses buffers that are written to disk by an asynchronous writer thread. Additionally, ETW gives you the ability to enable and disable logging dynamically, making it easy to perform detailed tracing in production environments without requiring reboots or application restarts. Using a buffering and logging mechanism implemented in the kernel, ETW provides a tracing mechanism for events raised by both user-mode applications and kernel-mode device drivers. Winsock tracing uses Event Tracing for Windows (ETW), a general-purpose, high-speed tracing facility provided by the operating system. Winsock tracing provides a more verbose tracing level which can log additional information to catch buffer corruption and poorly written applications.
PROXYCAP WINSOCK ERROR CODE
Very often, the returned error code does not explain why the error happened, especially when the error is initiated by the underlying network transport. When an unexpected error occurs on a socket, the main clue to diagnose the problem is the error code returned. Starting with Windows 8 and Windows Server 2012, use Windows Filtering Platform. Layered Service Providers are deprecated.
