+          **Deprecation Notice**: This collector is no longer the recommended method for Windows monitoring and will be removed in a future release.

+          The official Netdata Agent for Windows now provides a robust and user-friendly solution for real-time system and application performance monitoring. By installing Netdata on your Windows host, you'll gain access to a wide range of metrics and visualizations without the need for additional collectors or complex configurations.
