I am not sure that it's really feasible to decouple feature and security updates though. With Microsoft releasing two major feature updates a year, how many variations of this can they support if anyone along the way decides to freeze their current set of features and only get security updates for them? Regardless, as a heavy Win10 user across several machines I've found the whole "disruptive" / "spyware" / "crapware" FUD being pushed by some HN posters to be way overblown. Yea, there have been a few annoyances such as the OneDrive ad that showed up a month or two ago, but these are all extremely minor compared to the mountains of advertising and tracking crap we get hit with every day from web sites, apps, and search engines.
