Question

I have just completed an update. If I choose to shut the computer down, the Turn Off has a security shield over it with the options "click Turn Off to install updates and turn off the computer" or "click here to Turn Off without installing updates" How can this be when I just called for updates by going to the Security Center? If I click the first option, it shows update download. If I use the second option I get a message if you end now you will lose any unsaved date. I have nothing running.
