The simple solution is to clear the Default Folder under the users profile. LIke Google Chrome the Edge brower puts all the user data in one location. Below should help you create a a batch file. You first kill the tasks for Edge and clear the "Default" folder. You can go up a level a few folder levels to %localappdata%\Local\Microsoft\Edge\User Data. However, I found the Default folder the most useful. If you use One Drive to save favorites you shoud be safe to use the below. If not you could backup favorites but copying the htm file under the default fold somewhere and copy it back after clearing folder. Hope this helps
