I had updates available for windows 8.1 on my laptop last night but they failed to install and then my computer tried to restart and it can up saying 'We couldn't compete the updates. Undoing changes. Don't turn off your computer' but then it stayed like that for a long time. After force restart, the same message still comes up and it's been there all morning. I have a Dell Inspiron 15 5000 series. Can someone please help? I can't get past this screen at the moment.
