Can I disable Microsoft Edge here?

Hello mnlady205,
 
Welcome to the Webroot Community,
 
IMO I would just change Microsoft Edge browser to the browser of your choice by chenging the default browser to IE, FF or Chrome. Have a look here on how to do that.
 
Note: You need to install your browser of choice prior to following this process so it is available as an option.
 
Lets get started:
 
First click the Start Button in the lower left corner of your main Windows screen (or press the Start Key on your keyboard then type/search for default browser (1).
Next you will see an entry at the top of the Start Menu that says Choose a default web browser (2).
Click that entry to continue.

That will open up the Settings>System>Default apps area with the Web browser option selected.
Click on that entry to continue.

In the resulting pop up menu just click on your preferred browser.

Once you have selected your preferred browser it will now show as the default.

Just close the window and you are done.
From this point forward any clicks on web links in apps or programs will result in your browser of choice opening up.
 
Hope this answers your question.
