Microsoft is quietly rolling out an experimental Copilot capability called PC Insights that lets Windows 11 users ask, in plain conversation, why their machine feels slow — even as the Copilot app itself can consume up to 1GB of RAM. The opt-in feature is being tested in a staged rollout to a subset of U.S. users and was surfaced through Microsoft support documentation and the Copilot app's codebase.

The AI that diagnoses your slow PC — while eating up to 1GB of RAM itself

Microsoft is quietly testing PC Insights, an opt-in Copilot feature that lets Windows 11 users ask, in plain language, why their machine feels slow. The irony: the assistant hunting for bottlenecks has become one of the heaviest apps on the system.

1GB

peak RAM the Copilot app can reach when active

~850MB

automatic fixes — read-only, it can only diagnose

The memory paradox

Copilot's footprint: native build vs. today's web hybrid

<100MB

Old native
WinUI build

~500MB

up to 1GB

The shift back to a WebView2 + bundled Edge fork made Copilot up to 10× heavier than its native predecessor.

Ask in plain language

"What's my current CPU usage?" "Room to install a 100GB game?" "What USB devices are connected?" "How's my battery health?" "Is my antivirus running?"

Reads system telemetry via Windows APIs — CPU, RAM, GPU, storage, peripherals, network, battery, antivirus, BIOS and folder sizes — but not the contents of personal files. Gated behind explicit "ask every time" or "always allow" permissions.

The appeal

A conversational health check for less technical users
No digging through Task Manager or Settings menus
Ask questions instead of interpreting graphs

The catch

A memory-hungry assistant hunting for slowdowns
Read-only — describes problems, can't fix them
Awkward beside Microsoft's "lighter, faster" Windows push

Still an experiment. PC Insights is a staged, opt-in rollout to a subset of U.S. users via the Microsoft Store version of Copilot — not yet reaching everyone. Its real test: whether future versions can act on the problems they detect, not just describe them.
