In Windows 10 1607 (Anniversary Update), the Windows Update setting no longer offers a drop down menu to disable updates.
However, you can still turn off Automatic Updates with Group Policy.
With the help of the networking monitoring tool, I could see that Windows downloaded a couple of megabytes from Windows Update, but then stopped.
Even after several hours, no new updates appeared in the Update History.
The Windows Update settings usually displays the updates that are currently downloaded.
