My daughter has had her new computer for a month, running Windows 8. It seems no one set up the automatic update (it's all in Turkish so someone has to do it for me) so now, when we couldn't download windows 10 we realised this was because we needed to first update 158 updates to windows 8. This took all night. When we, following instructions, restarted the computer, it stayed at 'restarting computer' for nearly two hours. It is still there. I'm assuming something is wrong. What should I do?
