I've installed Win10 on dozens of machines and I've never seen ads on the lock screen, in the taskbar, and in notifications like the article talks about. Maybe because I always say "no" to all those creepy tracking/advertising ID type options on the initial config screen and I always say no to Cortana at the same time. What I heard (and it seems reasonable) is that MS included games like Solitaire and Minesweeper in 3.1 as a soft way of training the enormous user base who were using PCs for the first time in mouse functions like click, drag, right click and click precision. I guess now that everybody knows that , MS sees no practical reason to keep those games free.
