On Windows 7 SP1 and Windows 8.1, you might recently have got the update KB3035583. It installs folders and functions to promote the launch of Windows 10 and of course, it calls home to do that.

See more details in this article.

Luckily, you can un-install this update, or, if you have not installed it already, hide it in the "recommended updates" screen.

If you are on Windows 7 and don't plan to upgrade to Windows 8.1 or Windows 10 you can also uninstall:
