Are you new to tech? This is something very easily tested for yourself, what's the confusion?
I've been a tech for 27 years and this is yet again a disgusting business practice from one of the most corrupt companies on earth, Microsoft.
To save the so called tech person time, I tested myself, took less than a minute, it defaults to EDGE regardless of the settings telling you that it will choose the default browser, as i said, another disgusting act from Microsoft against its users, that they obviously don't care about, maybe if we were money?
