PC Insights: Windows 11 Copilot Diagnoses Performance Issues Using Live System Data

Microsoft has quietly begun piloting a new Copilot capability, “PC Insights,” that lets Windows 11’s AI assistant read live system telemetry and identify the likely sources of performance slowdowns.

The limited rollout is reportedly confined to select users in the United States, with no public timetable for broader availability.

If finalized, PC Insights would change how many users troubleshoot sluggish machines by turning diagnostics into a conversational exchange with Copilot.

Windows 11 Copilot Diagnoses Performance Issues

PC Insights runs as an opt-in Copilot module that pulls data directly from Windows APIs to monitor CPU, RAM, and GPU load, along with total and remaining storage space.

It can calculate whether there’s enough disk space available before installing software and itemize how much space folders such as Downloads or Documents consume, without opening or reading individual files unless the user explicitly grants permission.

The feature also extends to peripheral and subsystem monitoring: attached USB devices, external drives, printers, webcams, Bluetooth and Wi‑Fi connection states, battery health, antivirus status, system specifications, and BIOS details are all within its visibility.

From a usability perspective, the advantage is clear. Instead of digging through Task Manager, Resource Monitor, and various settings screens, a user can ask Copilot why a laptop feels slow and receive an explanation grounded in real-time system data.

For example, after reporting that 87 GB of free storage remains, Copilot could immediately answer whether that space is sufficient for a specific game and which folders to clear to free the necessary capacity. That conversational diagnostic model simplifies triage for non-technical users and can speed resolution for IT support staff.

However, PC Insights sits at the intersection of helpful tooling and potential privacy and resource concerns. Microsoft emphasizes that the module reads aggregated telemetry and folder sizes rather than file contents by default, and that users must opt in for more intrusive access.

Peripheral and network state monitoring also raises reasonable questions about the scope of data Copilot may surface and where that data is processed, locally or in cloud-assisted models.

Clear, transparent controls and audit logs will be important to ensure users and administrators can restrict access and understand what is being collected.

Resource consumption is another tension point. Copilot on Windows runs an embedded private build of Microsoft Edge and has been flagged in independent benchmarks as a relatively heavy memory consumer, occasionally using close to 1 GB of RAM while idle.

That creates a paradox wherein the assistant designed to diagnose performance bottlenecks might itself add to a system’s resource load, particularly on lower‑end devices.

Microsoft has already responded to user pushback by removing some Copilot entry points from Snipping Tool, Photos, Widgets, and Notepad to reduce perceived bloat; whether PC Insights will maintain a lean footprint will be central to its acceptance.

Security teams and enterprise administrators will want to validate several aspects before wider deployment: exact data access semantics, local versus cloud processing of telemetry, protections against data exfiltration, and the feature’s privileged access model.

For managed environments, group policy controls or Intune profiles that govern PC Insights’ availability and permissions will be necessary to keep the feature aligned with organizational security policies.

Microsoft is pursuing a broader performance agenda for Windows 11, including plans to reduce baseline memory use and better handle heavy workloads, and PC Insights appears to be an extension of that effort into AI-assisted diagnostics.

But because the pilot has limited reach, final capabilities, resource demands, and the release timeline could change. Observers should watch for Microsoft to publish clear privacy documentation and enterprise controls before PC Insights becomes widely available.
