While checking out the user's Windows 7 Pro laptop, I checked off the Definition Update for Microsoft Security Essentials. When I started the update after the selection, I saw a message on the Windows Update that Windows 10 was being downloaded.
This person doesn't need Windows 10.
I don't know why this appeared. How can I block it?
For now, I've changed the setting to Download but let me choose whether to install them.
I would prefer automatic installation of important updates, but I don't want Windows 10 to auto-install.
