In the Settings app, under Windows Update, you can find the update history. That tells what update is was. So please tell that.
after this latest Microsoft update in February 2019, my laptop just shuts completely off. OFF. it does it whenever it feels like it with no warning. it happens when it's plugged in or running on the battery. I have to push the button to turn it back on. my updates are automatic so I don't know exactly what they were. i'm not sure if it was a Microsoft update or windows update. all I know is that it took quite awhile. my friend is also having the same problem. does anyone know what's going on with this? (I have windows 10)
