Freezes at "Windows Starting" Logo, then resumes normally?

Yesterday night my laptop installed an update and I remember it prompting me to restart my computer. Instead I chose the option to postpone the update. I erred when I forgot to restart my computer before going to sleep and instead had put it into sleep mode. Upon resuming windows, my screen was black and there was an error (which I failed to note but it was something about "logging in").

I tried force-powering off my laptop and upon reaching the "Windows Starting", I notice that the logo freezes. The computer appears unresponsive but after a couple of minutes, I am taken to my account log-in screen.

I read somewhere that this might be the result of a corrupt C file. Will a system restore fix the problem? (On the system restore there is a timestamp for "Windows Update" of type "Critical" that was installed around the time I postponed the restart). Is there a way I can scan my computer for corrupted files?
