Today, when I started up my computer, it finished a Windows 8 update and I was able to log in normally. However, once in, a teal splash screen appeared, not allowing me to click on anything. It mentioned an update, and had a logo centered that read "A.I.", spelled out with the figures of people in side view.
I tried ALT+F4ing it, but it prevented me from taking any further action. Restarting caused the same effect, and when I used task manager to close its process it restarted my computer after a short while. I'm not sure what it is because I didn't catch its name in Task Manager. Any help would be appreciated, thanks
