Some people are tempted to turn off Windows Update completely to avoid getting the new operating system – don't. It'll leave your computer vulnerable to attack as you'll no longer get security patches.
Equating Windows updates with implicit safety because of their "security updates" is a false equivalency. You can run Windows securely without ever having done a Windows Update, if you take other, perhaps more conscious, thought-intensive and less convenient approaches. and besides, it frees you from getting the all-too-often borked update that completely (or worse IMHO, partially) hoses your system. (e.g. the "invitation" to upgrade to Win 10)
Nah, leave WU off, and simply use you head about what you do online.
