When a PC is slow, hangs, or feels laggy, Windows can record a detailed performance trace while the problem occurs. A performance trace is a separate binary file (.etl) that captures fine-grained timing data about CPU, disk, memory, waits, and similar activity. Microsoft's early-preview tools ETW MCP and WPA MCP let an AI assistant ask questions about that .etl file in plain language, so you spend less time hunting through unfamiliar charts and tables.

Microsoft’s code-testing-generator checks whether AI-written unit tests actually work
Microsoft’s open-source code-testing-generator does more than create unit tests: it compiles and runs them, checks their assertions, and uses mutation-style checks to determine whether they can detect real code changes. The AI agent supports.NET, Python, Go, TypeScript, Java, and Rust through GitHub Copilot CLI and preview plugin support in Visual Studio Code.
