Not OP, but I use Chrome and Edge does not open up randomly. There is literally zero issue with it.

You conveniently leave out all the hoops you have to jump through every couple months to make sure it stays that way. Every now and then some windows update adds another shortcut to your task bar, resets it to be the default browser, and other shenanigans.

That never happened to me.

I have mac, Windows and Linux machines.

It's funny to observe HN bias against Windows.

Makes me wonder what other strong biases I'm being exposed to without noticing.

Bias is when people don't like a thing you like, right?

This is stuff I witnessed happening at work, and with relatives still on windows; the internet (not just hn) is full of rants about it, even some news outlets picked up on how Microsoft aggressively tries to shove Edge down everybody's throat. And you show up here claiming that never happened to you and that it's just HN folks hating on windows. How can anyone be in such denial?

It does and sadly it is not random

Try opening Edge and you will realize that is has imported all the Chrome session/cookies etc and now you are logged in those sites in Edge. This setting is on by default.

Try opening a link from teams

Just found that out the other day, Teams has its own preference for what your standard browser is and somehow its edge

Opens in chrome.

In Teams Classic, Teams for Schools, Teams for Personal use, or New Teams?
