So it hangs at "Restarting" ONLY after doing Windows Updates or McAfee? That is very very odd, never seen it hang at "Restarting" before only during windows updates. "Configuring WIndows Updates" maybe, but that's a different stage.
Makes no sense really.
In the first instance try running
at an elevated command prompt. Then reboot.
Also after that, try installing all available updates manually (both important and optional - you can ignore Win10 and Skype updates) so that no remaining updates are appearing in the list.
This time, don't click the "restart now" prompt, instead do "shutdown -r -f" at command prompt.
