Computer Turns on at 3:30 a.m. and Does Windows Updates?

[turkey3_scratch]

While I was sleeping peacefully last night, I woke up to my fans and LEDs on my computer, which just happened to turn on at 3:30 a.m... By itself. I know about LAN wake, and while it was enabled in the BIOS, everyone in my house was asleep, and I highly highly doubt this happened. The computer was shut down; in Windows power settings, I have the shut down button actually shut down the computer, not put it to sleep.

So my question is, is this a Windows 10 thing? Turns on the computer in the middle of the night to do updates? It was a major update, one of the big Windows updates that has the circular loading bar with the percentage in the middle.

it is most likely windows 10 thing, my win10 laptop likes to recommend installation of updates at 3:30am too. (and will do so too unless another time is set)
