Removing Microsoft Edge can stop some installed apps, sites installed as apps, and Edge-backed widgets from working. Microsoft names the Copilot app as an example of a Progressive Web App (PWA), and says some Widgets features and the News Feed depend on Edge. Windows Search web results are powered by Bing and open in Edge in the flow Microsoft describes. Which of these effects you see depends on what is installed on your PC and how it is configured.
What stops working when Edge is removed
Microsoft’s support article “Apps and widgets that depend on Microsoft Edge” (accessed 2026-10-07) lists the experiences that rely on the browser. The breakage is feature-specific rather than system-wide.

Installed Progressive Web Apps and sites installed as apps
A PWA is a web app that runs in its own window. Microsoft says installed PWAs stop working if Edge is uninstalled, and it gives Copilot as one example. Sites you have installed as apps through Edge fall into the same category. If you rely on either, expect them to fail to launch or to lose their functionality.

Microsoft says some Widgets features and the News Feed depend on Edge. The word “some” matters: the source does not say that every widget breaks, so test the widgets you actually use before assuming a specific one is lost.

Windows Search web results
According to Microsoft’s description, web results in Windows Search are powered by Bing and open in Edge. Removing Edge therefore affects the handoff to the browser for those results. The same source does not say that local file search is disabled, and you should not assume it is.
Why Edge and WebView2 are different things
Most of the confusion comes from treating two components as one. The Edge browser is the application you open to browse the web. Microsoft Edge WebView2 Runtime is a separate component that lets applications embed web content inside their own windows. Microsoft’s WebView2 end-user FAQ (accessed 2026-10-07) states that “Microsoft Edge can be uninstalled without causing a problem for WebView2.”
| Component | What it does | Effect of removing the Edge browser |
|---|---|---|
Microsoft Edge browser (msedge.exe) |
Full browser; default browser on Windows; supports some web-based apps | Installed PWAs, sites as apps, and some Edge-backed widgets and News Feed features stop working |
Microsoft Edge WebView2 Runtime (msedgewebview2.exe) |
Lets apps such as Widgets, Teams, Office, Outlook, and Weather display embedded web content | Microsoft says WebView2 continues to work without the full browser |
| Microsoft 365 features that need WebView2 | Some features require the runtime | Affected only if the runtime is missing; the Microsoft Learn Microsoft 365 Apps documentation states the runtime does not install or require the full Edge browser (accessed 2026-10-07) |
The practical point is that deleting the browser and deleting the runtime are separate decisions with separate consequences. Removing the runtime is not a way to remove Edge, and it can break apps that depend on it.
Recovering from a removal that broke something
If you removed Edge and a dependent feature stopped working, work through the following in order.
Rank #3
- Used Book in Good Condition
- Reinstall Edge from
microsoft.com/edge/download. Microsoft’s support article says this is the route if Edge was removed by accident. - If an app’s embedded content is blank or failing, check the WebView2 Runtime separately. Microsoft says the runtime is preinstalled on Windows 11 and present on most Windows 10 devices. Apps can check for it and reinstall it, and managed organizations can deploy it.
- If your goal was only to stop using Edge, change your default browser instead of uninstalling Edge. Microsoft’s “Why can’t I uninstall Microsoft Edge?” support article (accessed 2026-10-07) explains its position and notes that you can install another browser and make it the default.
Microsoft recommends keeping Edge installed and updated, because that is the configuration in which the Edge-dependent experiences are designed to work.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What not to assume
- Uninstalling Edge does not, on the basis of Microsoft’s pages, mean the operating system becomes unstable.
- It does not disable all Windows search. Only the web-result path tied to Edge is described as affected.
- It does not remove WebView2, and removing WebView2 does not remove Edge.
- The results are not identical on every PC. Uninstall options and system behavior can vary by Windows build, region, edition, and management policy. The sources reviewed do not provide an exhaustive per-build list, so check current Microsoft documentation before following version-specific instructions.
Before you remove anything, list your installed PWAs and app-sites, note which widgets you use, and check whether any Microsoft 365 or third-party app you depend on embeds web content. That inventory tells you what will break on your machine.
