UEFI BIOS Update via Windows Updates?

One of the user tech's ("rockstar") on the Dell Community Forums reported he got a BIOS update for a Dell via the Windows 10 Updates.

Was this a fluke or is this something that is coming for all or selected PC's?

I know about the Dell software. The screenshots he posted were the Win 10 updates, not the Dell "Support Assist".
The person that posted (and most of us "techies" on there) do not use the Support Assist.
(I'm also one of the "rockstars" on the Dell forums).

Yes, I have had a UEFI firmware pushed via Windows Update.

Thanks for the confirmation. I wonder why its not been widely publicized?
But its scary. On some PC's if a BIOS update is corrupted there is no recovery. Motherboard must be replaced.

Well, looking at, actually, I might have been mistaken. This is what my Device Manager shows:



Then if I delete the device, checking the box to uninstall the driver, and reboot, it comes back again like this:



Then, if I manually update the driver, it goes back to the first screenshot, ver 1.9.0. Thing is, my UEFI firmware version is 1.10.0 and it was updated manually with a download from Dell Support website. So, I think maybe what is being seen in device manager as an "update". It is the driver that interfaces with the UEFI firmware for various functions, not the firmware itself. The version number shown in Device Manager is the version number of that driver - not the version number of the firmware itself.

I have that on a Dell Inspiron 15 Laptop and my home built desktop with an ASUS ROG Z170 motherboard.
It shows
Device Type: Firmware
Manufacturer: Microsoft
Location: on Microsoft UEFI-compliant system
