I must be the fortieth to advise you to install Linux.

Use Waterfox to confuse Windows and boost your performance

Om Windows 10 you have the option to turn off showing news about new features. I guess it would cover this. Try Google it.

Not a solution since I don't use w11 but whatever solution you find, it's most likely going to get reverted after a update since Microsoft, hooray!

But as others suggested maybe try ShutUp10, not sure if it has a fix for this but try your luck I guess

I freaked out yesterday when I got this pop up too. Like, okay, I heard about ads in Windows 11, but stay the fuck out of my 10.

Submit 🤣

Bing has honestly been a lot better for me than google. I refused to use it for so long because it was just a joke when it first came out. But I started not being able to find any decent search results on google and the entire first page is now ads versus just the first few results. Bing also has an AI thing that will just give you a straight answer to a question and links to where it found it. I'd say to give it a try.
