1903 & WU Settings

As needed, Windows Update notifies when to restart computer. 1903 brings a new setting in WU (circled in screenshot) and I can't find a more detailed explanation for it. Am I correct in thinking if this is turned on, the computer will restart right away as opposed to simply notifying a need to restart when convenient?

That has been there since 1809. It just means that you can allow the OS to use its old behavior after updating, instead of waiting for the user to decide to restart after updaing.

Thanks for information. I prefer to decide when to restart so I'll just leave it alone.
