EdgeDeflector can intercept anything that forces Microsoft Edge to open and redirects it to your default web browser.
There are numerous applications out there that need to open a web browser, and often it will force Edge to be the browser of choice. Many of us prefer a different browser and use it all the time.
If you dismiss the initial dialog to choose to use EdgeDeflector, or choose the wrong app, you can apply the change in the Windows Settings app: Apps: Default apps: Choose default apps by protocol: Microsoft-Edge.
All you have to do is install EdgeDeflector, and it runs transparently in the background. You won't even know it's there.
