hi I have windows 8.1 and it's been stuck trying to update for hours. The message that the screen is stuck on says "working on updates 86% complete don't turn off your computer" it has been on that screen for hours occasionally it will restart its self but soon as it reboots it's instantly on that screen again ...I have also tried a hard reboot hoping to maybe get in through safe mode but I am never given that option it instantly goes to this screen. Does anyone have any suggestions on how I might can resolve this issue thanks.
