Microsoft's Copilot Update Hijacks Default Browser Links

Microsoft's latest Copilot update does something the company frames as helpful but functions as a takeover: every link you click inside the app now opens in a Copilot side panel, powered by Edge's rendering engine, rather than the browser you chose and set as your default.

Microsoft describes the intent as keeping content "in a sidepane next to your conversation instead of a separate browser window, so you don't lose context." The company hasn't said whether any of this is opt-in.

When the OS vendor controls the platform and routes your links through its own browser engine by default, privacy concerns pile up. For as long as anyone remembers, clicking a link has meant one thing: your default browser opens, with your settings, your extensions, your saved passwords, your chosen security configuration.

And Microsoft is now overriding it without asking. Users don't get their browser. They get Microsoft's rendering surface, wrapped in an AI assistant they may not have asked to be involved in their browsing.

The side panel is only one piece of the update. With user permission, Copilot will also have access to the context of tabs opened in a conversation, allowing it to answer questions, summarize across tabs, or help draft text based on what's on screen. Tabs are saved with the conversation for later return. Users who choose to enable it can also sync passwords and form data.

Microsoft stated: "As part of this update, some features like Podcasts and Study and Learn mode from Copilot.com are getting added, while others may be pulled back while we iterate on the experience; we will add priority features back in before the updated app is generally available."

The rollout is currently limited to Windows Insider channels, Microsoft's public pre-release testing program, reaching version 146.0.3856.39 and above.

The company calls it context preservation. What's actually being preserved is your attention inside Microsoft's ecosystem.

This move represents a significant shift in how Microsoft approaches user choice on its platform. By intercepting link clicks and forcing them through its own rendering engine, the company is essentially creating a walled garden within its own applications. Users who have carefully selected their default browser for specific reasons—whether for privacy, performance, or compatibility—are now being funneled through Microsoft's preferred path without consent.

The privacy implications are particularly concerning. When links open in Edge's rendering engine regardless of your default browser, Microsoft gains access to your browsing data through a channel you didn't explicitly open. This creates a potential data collection vector that bypasses user preferences and privacy settings established in their chosen browser.

For developers and power users, this change could create significant workflow disruptions. Many professionals rely on specific browser extensions, developer tools, or enterprise configurations that may not be available or may behave differently in the Copilot side panel. The forced migration to Microsoft's rendering surface could break established development and testing workflows.

The timing of this update is also noteworthy. As AI assistants become more deeply integrated into operating systems, companies are finding new ways to keep users within their ecosystems. By making the AI experience seamless and context-preserving, Microsoft is betting that users will accept the trade-off of reduced browser choice in exchange for convenience.

This strategy mirrors moves by other tech giants to create integrated experiences that are difficult to leave. Apple's ecosystem lock-in, Google's integration of services, and now Microsoft's browser hijacking all represent different approaches to the same goal: keeping users engaged with a company's products and services for as long as possible.

For now, the feature is limited to Windows Insiders, but history suggests such changes often become permanent for all users after testing. Those who value browser choice and privacy may want to monitor this development closely or consider alternatives if Microsoft proceeds with a wider rollout.
