This is my start menu in Windows 11, so I'm also curious about all the hubbub. I will admit I had to get rid of a load of unwanted links when I first got the computer but I've never seen adverts beyond that and that it suggests Microsoft Edge in certain contexts.
It's like I've told a number of my bosses in the past: you have to treat the people making your money for you well, or they just fuck off. They never listen, and everyone always just fucks off. I'm a soothsayer!
