Today after I took my laptop(a surface book) out of my bag that's previously in sleep mode, it was very hot. When I opened it up, the screen would not turn on so I held down the power button and forced a restart.

After rebooting, it started a Windows update, which took about half a minute. After it was done, I went into settings > update and security, and the "update" that just happened did not appear in the logs. I also set my computer to update only in the night, so this update was obviously not a planned update.

What happened? Is my computer infected by a virus? Why was there a random update with no records of any kind?
