My solution: If you are running any antivirus/malware software, remove it from your system. "Pausing" it, will not work, it has to be removed and then reinstalled after the update is complete. Also, some drivers for some printers can cause this update to fail. Unplug all devices from USB ports. Reboot your system, and then perform the update. Then connect all USB's that you removed and reinstall the antivirus/malware software if you had any. This worked for me, hopefully it will for you as well.
