Which of the following could cause the Windows 7 system to run the disk checker upon startup?
  1. The system was properly shut down.
  2. The system has been infected with a virus.
  3. A power outage caused the system to suddenly shut down.
  4. The user exceeded the number of password attempts.
Explanation
Answer: C - A power outage that causes the system to suddenly shut down could cause the Windows 7 system to run the disk checker upon startup.

Key Takeaway: Every version of Windows since XP will run a diagnostic disk checker when booting up after an unexpected shut down, for instance due to a power outage. This is because if some files weren’t closed currently, they could cause errors when Windows starts back up. Although a virus infection could cause the system to shut down improperly, it is not the most likely cause of a reboot.
