Jo-Anne,
You're pointing to "notifications" via Windows Automatic Updates.
There is an issue of the time at which your individual pc is set to kickoff
your local automatic update client program. This normally runs once a day.
Notifications via automatic updates takes time to communicate with the MS
servers and back to your pc. It is just simply a matter the time it takes,
and the speed of your internet connection.
This does not account for your computer being turned off (powered down). If
that is the case, you're looking at more delay.
Monthly updates are "typically" released after noon-time Pacific time zone.
Lastly, the Express option at Windows Update simply skips non-priority &
optional updates.
Your setting (your choice) for Automatic Updates controls whether or not
"automatic updates" automatically downloads or updates. Do not confuse the
web Windows/Microsoft Updates with "automatic updates".

MS always publishes "advance" notices of upcoming updates on at least a
couple of web pages.

Announcements are made a few days before each set of scheduled monthly
updates.
I hope this has helped and possibly clarified a few things. Also, hoping I
got the right gist of the basics. <w>
