mysterious Windows update message

I booted up and got a message from Windows saying that it had done an automatic update that involved a reboot. But there was no mention of this when I last turned off the computer. It's not possible Microsoft turned on my computer to perform an update, is it? If not, then what happened here?

 

did you check what was updated last under the list of previous updates? it might offer a clue

 

I get Windows Defender updates that seem to slip in without needing re-boots. An aunt of mine often turns her computer off as it is re-booting after installing updates. She wonders why it freaks out sometimes when she turns the computer on in the morning. I'd definitely follow Cudni's advice & have a look in View Update History.

'It's not possible Microsoft turned on my computer to perform an update, is it?'

Jeez...don't give M$ ideas like that!
