[Full Guide] Disabling the Microsoft Edge WebView2 Runtime

/ James Masterson

If you’re a Microsoft Edge user, you may have encountered the Microsoft Edge WebView2 Runtime at some point. This technology, built on the underlying web platform, allows developers to incorporate web code into their native applications, embedding web content directly into those apps.

As a result, hybrid applications can function properly without requiring the user to open a browser window. While the WebView2 Runtime is installed automatically with Microsoft Office apps, it can also be installed offline and used in other environments. However, if you’re running low on disk space or notice high CPU usage in your Task Manager’s Details tab, you may want to disable it temporarily or stop it from auto-installing.

In this article, we’ll discuss the Microsoft Edge WebView2 Runtime, how to install and uninstall it safely, and how to disable it using the command prompt or developer control.

What is Microsoft Edge Webview2 Runtime?

Microsoft Edge WebView2 Runtime is an environment that enables developers to incorporate web code into their native applications. This runtime environment uses the latest rendering engine from Microsoft Edge, allowing developers to display web content in their applications. By doing so, developers can create hybrid applications that offer users a seamless experience while integrating web technologies.

The Edge WebView2 Runtime is included in the evergreen standalone installer of Microsoft Edge. It is installed automatically with Microsoft Office apps or offline using the full-blown installer. Once installed, the WebView2 Runtime executable file is in the Program Files or Downloads folder.

The Edge WebView2 Runtime is designed to function properly in online and offline environments, enabling developers to embed web content and offer users a more feature-rich experience.

Do I Have Edge WebView2 Installed on My PC?

To check if the Microsoft Edge WebView2 Runtime is installed on your computer,

  1. Simultaneously press the Windows key and the letter “I” to open the Settings app.
  2. Navigate to “Apps,” followed by “Apps and Features.”
  3. Inside the search bar, type “WebView2”.
  4. If the Microsoft Edge WebView2 Runtime appears, it is installed on your computer.

Does Uninstalling the Edge Browser Also Uninstall Edge WebView2?

There is a common misconception that the WebView2 runtime is a component of the Edge browser and can be uninstalled by removing the browser. However, this is not the case.

The WebView2 Runtime is a distinct installation that operates independently from the Edge web browser. Although both employ the same rendering engine, they utilize different files and are installed separately.

Should I Delete Microsoft Edge WebView2 Runtime?

It’s not advisable to uninstall Microsoft Edge WebView2 Runtime unless the component has a significant problem. This is because many apps and Office add-ins, such as the File Explorer PDF preview, New Media Player, and Photos app, rely on it to function correctly. Uninstalling it may result in these apps malfunctioning or not working altogether.

Microsoft Edge WebView2 is now an essential part of the operating system since Windows 11, and for Windows 10, developers are encouraged to build their applications using the WebView2 runtime.
