Oh hech yes. Home users are notorious for not installing updates. Of course we as IT people deserve some of the blame ourselves. Our employees, customers, family members, etc. are taught (by us) to never click on anything they don't understand or think they need. Instead of calling for help or guidance they just leave the notifications sitting in the system tray.
I *wish* they'd stop calling for help/guidance. Its usually well after the fact of "I downloaded..." or "i clicked on..."
