IEToEdge BHO is a Browser Helper Object installed as an add-on in Microsoft Internet Explorer. This add-on causes Internet Explorer to close and redirect to Microsoft Edge anytime Internet Explorer is opened.
To remove / disable the add-on do the following:
- Browse to "C:\Program Files (x86)\Microsoft\Edge\Application\85.0.564.63\BHO"
- Delete all files that contain "ie_to_edge" in the filename.
You should now be able to launch Internet Explorer again without it redirecting to Microsoft Edge.
