FWIW, the professional edition of windows 10 also comes with ads for games pre-installed in the start menu, I guess that's just the world we live in now...
Edit: I feel I should add, in fairness, that this has to be done (the removal) per account. I suspect that there is a system directory somewhere that is used as a template but I have not so far bothered to figure out where it is. I guess I've just gotten too accustomed to the 'Unpin from Start Menu' dance.
They can haphazardly reappear in time. I've seen this happen on 2 completely unrelated PCs.
It's probably just bugged. I've found the W10 Start Menu in general to be dodgy. The keyboard-driven search seems like it's totally nondeterministic, e.g. exact string matches for the name of something in Control Panel sometimes finds it and sometimes doesn't.
The search speed is vastly worse than what it was on windows 8. A part of me wonders if that's due to the conversion from native languages to html+css+js for the start menu, but even so it's significantly laggy for that.
Another thing that really annoys me is that web results pop in above local results on the computer. I almost never search Bing via the start menu, and I'd love for a way to disable that but I also realize it's their main strategy for monetization for win 10 now that they're doing free rolling releases.
