I uninstalled update KB3035583 and blocked it when MS first sent it out several months ago. Then when I installed the last batch of patches in December it installed KB3035583 anyway. Before Windows 10 was released I was looking forward to it as Windows 8 done right. I was a little concerned about the rolling release approach, but was cautiously optimistic. But given their heavy handed approach on forcing windows 10 on people, and all the spyware included in it, they have destroyed any goodwill and trust they built up in recent years. Trust they need if they expect people to buy into their new software-as-a-service approach. My wife's next laptop will be running Linux or Mac OS X, which is not a big deal as she has used both in the past.
