Microsoft is pretty sneaky. They camouflage their Windows 10 downloader, KB3035583, as a recommended Windows 7 update with no indication of what good this update does. Only by clicking on the first link is its true intention revealed.
As a contrast, the dreaded KB976002 browser choice update was well marked with its intention even in its (long winded) title. Luckily, we don’t see that update anymore.
