Windows is transitioning from being software you run to being an experience that Microsoft provides to you. The pattern of pushing new features to users unpredictably and without the option to refuse is clearly inappropriate in the first model but natural in the second. As a power user I strongly prefer the first model, but I recognize that most people these days might be ok with having their computer work like a website they access or an app they run on their phone - something they have no control over the state of.
