> And I don't think they're actually paid ads, for either the suggested apps or the rare occasion they've put an "ad" as the lock screen background. They've promoted the Surface on it before, and then for Tomb Raider, I think they were mostly pushing the idea of "hey, you can get games in the Windows Store now", rather than it necessarily being a paid campaign with the game studio.

So you're saying MS doesn't profit if you buy a Surface or something from the Windows Store?
