Microsoft Tests AI-Powered Copilot Tool to Diagnose Windows 11 Performance Issues

Microsoft is gradually testing a Copilot feature called PC Insights in the U.S. that lets the assistant query Windows system APIs for real-time hardware and performance data (CPU, RAM, GPU, storage, peripherals, battery, network, BIOS) to provide personalized troubleshooting; file content access requires explicit permission and the feature is not yet widely available. The report highlights potential performance impact (Copilot can use ~1 GB RAM while idle), describes available telemetry fields and permissions limits, and notes Microsoft has not announced general availability.
