I had to do a clean reinstall of Windows 10. While updating all Microsoft software and HP drivers, etc. (& there were so many of them) my computer said it needed to restart. Not of of the updates had been downloaded/installed yet. Since this is not unusual in my computer experience, I chose to restart now instead of waiting until later. My computer screen has been saying "Restarting" with the little white dots going round & round for the past 2 hours. Should it be taking this long to install whatever it is to install and then restart??
