Windows 11 introduces a redesigned Copilot app that shifts from a native application to a web-based version powered by Edge, leading to significantly higher memory demands.
New Copilot: Smooth but Resource-Intensive
The updated Copilot app, now available in the Microsoft Store, replaces the prior native version built on the WinUI framework. This latest iteration functions as a hybrid web app running on a dedicated instance of Microsoft’s Edge browser.
Users experience a seamless interface that mimics a native app, complete with the most recent features from the web-based AI assistant. It operates fluidly, delivering responsive performance during interactions.
RAM Usage Spikes Draw Criticism
However, this browser-based approach comes at a cost. Tests reveal the app consumes up to 500MB of RAM when idle in the background, surging to approximately 1GB during active sessions.
In an era of rising RAM prices and growing concerns over memory efficiency—especially for systems with just 8GB—this change raises eyebrows. Many PC users prioritize low-resource tools amid tightening hardware budgets.
Behind the Edge Integration
The elevated RAM footprint stems directly from embedding Copilot within its own Edge browser fork, akin to launching the AI in a private browser tab. While this simplifies feature updates for Microsoft—avoiding the complexities of native app maintenance—it prioritizes convenience over optimization.
This move contrasts with recent commitments to enhance Windows 11 performance and curb excessive RAM usage. The app’s evolution has been erratic: it began as a native side-panel tool, transitioned to a progressive web app (PWA), reverted to native, and now adopts a web wrapper again.
User Reactions
Performance enthusiasts express frustration. One Reddit user commented: “Copilot went from a lightweight assistant to basically a hidden Edge browser eating up RAM. Cool tech, but terrible for performance conscious users.”
Despite the drawbacks, the app’s quick access to cutting-edge AI capabilities keeps it relevant for everyday tasks.
