もっと簡単な方法がある
Close the Edge application from the Task Manager (Ctl-Alt-Delete)
Type in a random word like "help" into the Search the web and Windows box near the start button.
Click on any of the web links that are suggested....the Edge browser will open in a new tab...the malicious tab will probably be in the background so don't click on it and wake it up.
Make sure your "Open with" page in Settings is set to the basic "Start Page"
Close the Edge browser normally selecting "close all tabs"
Re-open the browser.
