Microsoft is pulling the plug on the Microsoft Edge sidebar app list, a move that signals a decisive pivot toward AI-driven browsing experiences. The change will first affect users signed in with personal Microsoft accounts, with the app roster being phased out gradually. However, Copilot—the browser’s AI assistant—will remain untouched, underscoring its central role in Edge’s future.

What the Sidebar App List Actually Is

The Edge sidebar, introduced in 2022, was designed as a persistent panel on the right side of the browser. It housed quick-launch icons for web apps and services—think Office.com, Outlook, Skype, Spotify, Pinterest, and others—alongside browser-native tools like Collections, Performance Detector, and Games. One click could summon the full app in a pane without leaving the current tab, positioning Edge as a productivity hub.

For power users, the sidebar’s app list was a productivity booster. For casual users, it often became a cluttered strip of icons they rarely touched. The list could be customized, but its default state included multiple Microsoft services and, in some regions, third-party apps. The retirement of this feature marks a significant shift in Edge’s interface philosophy.

The Retirement Plan: Personal Accounts First

According to a support document spotted by Windows Latest, Microsoft will begin retiring the Edge sidebar app list in the coming weeks. The process starts with users signed in using personal Microsoft accounts. These users will lose the ability to pin or access the specific app icons that currently line the sidebar.

Crucially, the sidebar itself is not going away entirely. The panel will remain as a container for Copilot—which now has its own dedicated icon and pane—along with other native tools that Microsoft decides to retain. The change is only about removing the vertically stacked app shortcuts like Office, Outlook, and third-party integrations.

Enterprise and education customers have not been included in this initial wave, hinting that the full removal across all account types may follow after feedback and iteration. Microsoft has not shared an exact timeline beyond “near future” and “beginning with personal accounts,” suggesting a cautious rollout.

Why Microsoft Is Retiring the App List

The reasoning isn’t spelled out in a blog post, but the writing has been on the wall since Copilot’s debut. Edge’s development resources have been funneled into AI features, from text summarization to image generation, all powered by Copilot. The sidebar app list, while functional, represented a more traditional, icon-driven approach to integration—one that competes for visual real estate with Copilot’s prominence.

By retiring the app list, Microsoft declutters the sidebar interface and directs user attention squarely at Copilot. This aligns with the company’s broader AI-first mantra across Windows, Office, and Bing. Edge, once just a browser, is being repositioned as an AI agent that happens to render web pages.

Moreover, telemetry likely showed that most users engaged with the sidebar primarily through Copilot or ignored the other apps altogether. Maintaining a variety of app integrations with differing update cycles and user permission models adds engineering overhead. Streamlining to a single, AI-driven sidebar reduces complexity.

Copilot: The Survivor and the Star

Copilot in Edge is more than a sidebar gadget—it’s the centerpiece of the browser’s evolution. It can answer questions about the page you’re viewing, rewrite text, generate images, and perform web searches in natural language. With the retirement of the app list, Copilot becomes the undisputed king of the right-hand pane.

Users will still access Copilot from the sidebar icon, the top-right toolbar button, or a keyboard shortcut. Because it runs in a dedicated sidebar pane, the experience remains as “side-by-side” as ever. The difference is that when you open the sidebar now, you won’t see a strip of apps to choose from—you’ll see Copilot ready to chat, with perhaps a few other persistent tools like Search or Collections if Microsoft opts to keep them.

This is reminiscent of the Copilot-first design in Windows 11’s latest versions, where the AI assistant has its own dedicated taskbar button and integration points. The browser is falling in line with the OS-level strategy.

Impact on Everyday Usage

For those who relied on the sidebar’s quick access to Office, Outlook, or other apps, the change will force a workflow adjustment. However, alternatives exist:

  • Pinned tabs: You can still pin Office.com, Outlook, or any other web service as a regular tab.
  • Favorite bar: The bookmarks bar can host frequently used apps.
  • Taskbar shortcuts: On Windows 11, web apps can be pinned to the taskbar via Edge’s “Apps > Install this site as an app” feature.
  • Edge’s new tab page: Customizable quick links serve a similar purpose.

The main loss is the ability to open an app in a side pane while keeping your primary tab active. For some, that multitasking convenience will be missed. Others may not notice at all, having long abandoned the sidebar for the main browsing window.

Community Reaction: Mixed but Resigned

On forums and social media, early reactions have been mixed. Power users lament the removal of a feature they customized heavily, while others shrug it off as a natural cleanup. A Reddit thread on r/MicrosoftEdge shows some users questioning why Microsoft couldn’t simply allow the sidebar to be more customizable rather than removing the app list entirely.

“I used the Office and Outlook icons daily,” one user wrote. “Now I have to open a new tab and navigate, which breaks focus.” Another countered: “Let’s be honest, Copilot is the only sidebar tool I ever used. The rest were just visual clutter.”

Critics also point out that Microsoft has a history of adding and abruptly removing features in Edge—from reading lists to legacy edge extensions—making reliance on any new feature feel precarious. Yet, the company’s AI push has been consistent, so Copilot’s permanence seems assured.

What This Means for Edge’s Future

The retirement is a tangible example of “AI-first” design philosophy in action. Edge is no longer striving to be a one-stop shop of integrated apps; it’s becoming an AI hub that navigates the web intelligently on your behalf.

Convergence with Windows Copilot is the next logical step. Currently, Edge Copilot and Windows Copilot are separate entities, but the underlying technology (Bing Chat, now Microsoft Copilot) powers both. Unifying them would let you ask a question in the browser and have it interact with your desktop, or vice versa.

We can expect further enhancements to Copilot’s sidebar pane—like persistent memory, plugin support, or integration with third-party services directly through Copilot rather than standalone app icons. The browser’s “sidebar” may become synonymous with “Copilot pane.”

How to Prepare for the Change

If you’re a personal account user who depends on the sidebar app list, now is the time to explore alternatives:

  1. Audit your sidebar apps: Note which ones you actually use.
  2. Recreate them: Pin them as tabs, add to favorites, or install as web apps.
  3. Embrace Copilot: If you haven’t tried it, test how it can replace some routine workflows—such as quick calculations, page summaries, or composing emails.

For enterprise users, no immediate action is needed, but it’s wise to plan for eventual removal. IT admins might consider group policies to customize the new tab page with essential internal apps.

The Broader Context: Browser Competition

Google Chrome and other Chromium-based browsers have also experimented with side panels—Chrome’s Reading Mode and Side Panel for custom pages come to mind—but none have pushed an app list as aggressively as Edge did. With Edge stepping back, it’s unlikely competitors will fill the gap with a similar feature. The industry trend is toward minimalism and AI overlays rather than multi-app dashboards.

For Windows users, the Edge sidebar app list retirement is another reminder that the OS and browser are converging around cloud and AI services. Local tools are being replaced by online versions accessed through Edge or Copilot.

Final Assessment

Removing the sidebar app list is a bold move that will frustrate a subset of power users but aligns Edge with Microsoft’s overarching narrative: Copilot everywhere. The sidebar itself remains, but its purpose crystallizes—it’s no longer a gadget drawer; it’s the Copilot portal.

This streamlining may also improve Edge’s performance and reduce feature bloat, which has been a common criticism. A leaner, AI-focused Edge could retain current users and attract new ones looking for a smarter browsing experience.

As the rollout begins, keep an eye on the Edge Dev and Beta channels for any indications of further sidebar customizations that might soften the blow. For now, though, the message is clear: your sidebar is for Copilot, and everything else is a tab away.
