So that Automatic Updates doesn't affect you while using the computer, set it to "Check for Updates but let me choose to download & install them". This way, you'll be notified of any updates, but you can install them when you're ready.
When I get this notification, usually on Update Tuesday, I normally install the updates during dinner, this way, all that I need to do is a reboot, & I'm ready to go. Just make sure you don't ignore any notifications, as many of these updates & patches are for our protection. Usually severe type of things like remote code execution are addressed in these updates. It's OK to wait a couple of hours, but not a couple of weeks.
