I have Windows 8 on my laptop and today I had a notification of an update when I started to power down. I set the computer aside and when I came back hours later the screen lit up when I touched the mouse and it read: Keep you PC plugged in until this is done. Installing update 1 of 1... I thought that if I turned it off and back on that maybe it would restart, but it went back to the spinning dots and same message. Now it is many hours later and it is still spinning with the same note. Any ideas on how to get the update pushed through?
