HOW TO change default browser of MS Word when I ctrl-click a hyperlink

I had a similar problem and just found an answer that worked for me which I will recreate here so we don't lose it. Try this but substitute IE11 for Edge.

In my case Chrome as already my default browser, yet following these directions I still had the option to choose 'Chrome' versus "use my current web browser" (apparently 'my current web browser' != my default web browser. Interesting choice of words there.)

You may have to hunt around for where you set the 'default programs' in Windows 10, these instructions were for Windows 7.

Click Start, select Default Programs

Click Set program access and computer defaults

Click Custom, and select Google Chrome

Click OK

Then, follow these steps:

Click Set your default programs

Select Google Chrome from the list

Click Set this program as default

Click OK
