What is the difference between `chkdsk` and `autochk`?

Windows

  • Chkdsk runs in Windows as a small box or in a DOS box within Windows, or in the Recovery console
  • Autochk runs in the blue boot screen and does the same thing that chkdsk does.

Autochk does essentially the same thing as Chkdsk but will only run during bootup (but during bootup it will only run if the system detects a cold boot or power off).
