Re: "sending activity history to Microsoft's servers"
Dude, get an intercepting proxy like Burp Suite and set your browser to use it. While Burp Suite is primarily intended for pentesters, you can use it to see how much shit phones home.
The results will probably surprise you. If used it to disable shitty extensions, disable default home pages, etc. All browsers are guilty.
