How do I disable Microsoft Edge Web Viewer?

To disable the Microsoft Edge Web Viewer, which typically refers to the Microsoft Edge WebView2 Runtime, you have two primary options depending on whether you want a temporary stop or a more permanent removal.

Understanding Microsoft Edge WebView2 Runtime

The Microsoft Edge WebView2 Runtime is a component that allows developers to embed web content (using Microsoft Edge's rendering engine) in their native applications. Many applications use this runtime to display web pages or provide web-based interfaces within the app itself, without needing a full browser window.

Disabling or uninstalling it can potentially affect the functionality of applications that rely on it.

Method 1: Temporarily Stop the Process (Task Manager)

You can temporarily stop the running process associated with the WebView2 Runtime using Task Manager. This will stop any active instances, but the process may restart when applications that use it are launched or when Windows services require it.

Here's how to do it based on the reference:

1. Open Task Manager: Press the keyboard shortcut CTRL + SHIFT + ESC.
2. Go to the Details Tab: Navigate to the "Details" tab within the Task Manager window.
3. Locate the Process: Scroll down the list of processes until you find the "Microsoft Edge WebView2 runtime process".
4. End the Task:
   • Click on the process name ("Microsoft Edge WebView2 runtime process").
   • Click the "End task" button, usually located at the bottom right of the window.
   • Confirm if prompted.

Note: Ending the task only stops the current process. It does not prevent it from running again in the future.

Method 2: Uninstall the Microsoft Edge WebView2 Runtime

For a more permanent approach, you can uninstall the WebView2 Runtime from your system. This will remove the component entirely.

Important Considerations:

• Uninstalling the WebView2 Runtime can impact applications that depend on it. Some apps may stop working correctly or lose certain features.
• You may need administrative privileges to uninstall software.

The reference explicitly mentions to:

1. Uninstall the Microsoft Edge WebView2 Runtime.

Typically, you would do this through the Windows "Apps" or "Programs and Features" settings:

1. Open the Settings app (Windows Key + I).
2. Go to Apps > Apps & features.
3. In the app list, search for "Microsoft Edge WebView2 Runtime".
4. Click on it and select "Uninstall".
5. Follow the on-screen prompts to complete the uninstallation.

Alternatively, you can access "Programs and Features" via the old Control Panel.

Uninstalling is the most direct way to "disable" it from running, but again, be aware of the potential impact on other software.

In summary, you can either temporarily end the running process or uninstall the runtime for a more lasting effect.
