when do auto-updates auto-install?

[yawnmoth]

I have Automatic Updates set up to install every day at 3:00 AM. I
also have a yellow shield in the bottom right portion of the screen
that says "Updates are ready for your computer. Click here to install
these updates". I click on it and see that there are four updates
available. Why haven't these been auto-installed? They've not
auto-installed for atleast 3-4 days.

One thing that occurs to me, as I type this, is that I run a scheduled
task, through the Windows Schedular, every hour on the hour. Could
that be interfering with this? It doesn't seem like it would since
I've had auto-updates try to reboot my computer while I was using it,
but who knows...

Any insights would be appreciated - thanks!

I believe, and you can check, the Automatic Windows Updates are performed
when time occurs AND the system is generally idle.
