As a maybe click bait avoidance measure, wanted to post a quick note explaining that the manual control under Windows Update -> Advanced Options is gone, but that's also a kind of "So What?" Unless your copy of Win10 is about to lose support, you still get the choice whether you want to update or not -- this is more about not showing users the option, and it can still be set with Group Policy, and probably a registry entry or two in Win10 Home, where Group Policy doesn't always work.
