Today's Windows update - "windows update" missing from control panel

Well apparently there was a massive Windows update yesterday - which installed itself this morning. I say massive, because despite having a good desktop CPU & fast SSD, it took more than 10 minutes to update, which is surprising.

I noticed the "Windows Update" options are now missing from the control panel - which does not allow me to see any details about the updates that were installed.
I also noticed a new icon in/near the system tray, the icon says "People" if you mouseover. I'm tempted to click it but was hoping to know what it is all about first.

You obviously got the Fall Creators Update yesterday. That's why you see the new People icon on the taskbar.
Just run Windows Update a few times until your pc is updated. Patch Tuesday was Tuesday, so W10 FCU got a newer version to fix bugs.
From experience with Windows 10 1709 (Fall Creators Update), go over your settings in the Settings app to change to your liking. Also recheck your power options, too.
You'll probably need to change a few settings to your liking again.

MS is slowly taking item(s) out of control panel but you can still access directly...

This one is still in 1709's Control Panel though. It's found in...
Control Panel > All Control Panel Items > Programs and Features > View installed updates.

Thanks for all the answers, it must have been the update to 1709 (current version)
