We’ve known since last year that Legacy Edge will exit support on March 9, 2021. But now Microsoft has revealed its plans for removing the browser from Windows 10.

“The new Microsoft Edge will be available as part of the Windows 10 cumulative monthly security update—otherwise referred to as the Update Tuesday (or ‘B’) release—on April 13, 2021,” the Microsoft Edge Team revealed. “When you apply this update to your devices, the out of support Microsoft Edge Legacy desktop application will be removed and the new Microsoft Edge will be installed. The new Microsoft Edge offers built-in security and our best interoperability with the Microsoft security ecosystem, all while being more secure than Chrome for businesses on Windows 10.”

The removal of Legacy Edge will occur across multiple Windows 10 versions, including 1803, 1809, 1903, 1909, 2004, and 20H2, and across all supported product editions, Microsoft says. (Remember that Legacy Edge was only made available on Windows 10, and not on previous versions of Windows.) If the new Edge is not yet installed, it will be installed when Legacy Edge is removed. Otherwise, just Legacy Edge will be removed.

There is one wrinkle for those businesses that use Legacy Edge in kiosk mode: The new Edge doesn’t support certain features provided by Legacy Edge. You can learn more here. And the legacy version of EdgeHTML, a rendering engine used by some Store apps—will continue to be supported. Microsoft recommends that developers use the new Edge-based WebView2 instead, of course.

For best results, you should of course upgrade to the new Edge before March 9. By which I mean before March 9 of last year, since this browser is a considerable improvement over Legacy Edge.
