Microsoft is automatically installing the WebView2 runtime on Windows 10 machines to support upcoming versions of the Microsoft 365 and Microsoft Office applications.

WebView2 allows developers to embed and render web content directly in their native applications, including JavaScript, HTML, and CSS. The WebView2 control is built upon Microsoft's new Chromium-based Edge browser.

In February, Microsoft announced that future versions of Microsoft 365 would begin to utilize WebView2 control to embed web content directly in the native applications.

To properly use the new Microsoft 365 applications, users would need to have the Windows WebView 2 Runtime, which Microsoft stated would be installed on March 8th, 2021.

This past weekend, on March 14th, Microsoft began auto-installing the 'Microsoft Edge WebView2 Runtime' on Windows 10 machines without any notification to users.
