DTrace

DTrace for Windows is a comprehensive dynamic tracing framework developed by Microsoft, designed to enable administrators and developers to diagnose kernel-mode and user-mode issues on live production systems without the need to restart services or reboot the machine. Operating through a command-line interface, it exposes thousands of instrumentation points across the operating system and running applications, allowing complex queries—written in the D scripting language—to capture timestamped data on CPU consumption, memory allocation, disk I/O, network packets, registry accesses, and thread scheduling in real time. Typical use cases include pinpointing the root cause of sudden CPU spikes in multi-process services, measuring the latency introduced by a filter driver, validating security audit policies by tracing system-call activity, or quantifying the disk seeks generated by a database engine during peak hours. Because probes are dynamically enabled only while tracing sessions are active, the runtime overhead is minimal, making the tool safe for mission-critical servers. The current stable release, version 2.0, succeeds the initial 1.x branch with improved compatibility for modern Windows builds, enhanced symbol resolution, and additional providers for container and Hyper-V tracing. As a system-level diagnostic utility, DTrace falls into the Developer Tools / Debugging & Tracing category and integrates seamlessly with WinDbg, Visual Studio, and CI pipelines for automated performance regression testing. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
