Log in to the Windows 7 or Windows 8 guest operating system as an administrator.
Click Start > Control Panel > System and Security > Turn automatic updating on or off. In the Important updates menu, select Never check for updates. Deselect Give me recommended updates the same way I receive important updates.
The great news is that you don’t have to do anything to get the latest updates, as they’ll automatically download and install when they’re available. (Unless you’re on a metered connection, then updates won’t download until you get them.)
