My suggestion is to download something like Windows Privacy Dashboard and disabling/uninstalling as much telemetry options as possible.

I've never got that kind of ad push, so i have to ask where you got it? Was it from using the search bar beside the start button? If so, maybe completely disabling and uninstalling Cortana might fix it.

switch to Bing

Straight up the same playbook that other entities used in the past to get your grandma to install unwanted search bars in internet explorer. No wonder Windows Defender is so advanced, Microsoft has a lot of experience as the developer of the most popular malware in the world.

Wait, you had this WHILE using chrome on win10? Jesus

Have you tried binging it?

Step one -- install Linux

~~Step two -- install Firefox~~

Oh, I almost forgot that most Linux distos come with Firefox pre-installed!

use a service like o&o shutup that'll cripple this among other bloat.

Switch to linux

The comments are weird. How often do you even see this? I feel like I remember it once and hit don't switch and thats it. Not sure why you keep getting it, but I also don't use edge so maybe that is why. I would imagine if there is a way to stop it it's in settings somewhere or possibly a local group policy maybe.

Using GNU/Linux instead

Write a complaint to the CMA about Microsoft’s anti-competitive and anti-consumer behavior.

Stop using Chrome.

By clicking yes you will never see it again 🙃
