Wait until you find out it's updating your motherboard BIOS/firmware (it tells you when it starts doing it!), and there's no way to stop it.

Not super great when the whole point of not upgrading to the latest BIOS was because it introduced a critical bug.

This only happens on Microsoft hardware though (or it is not Windows doing the update).

Good to know. But do any PC manufacturers do that in practice?

Not true. I only found out about this when my Acer laptop did it. :(
