Native shell is a program for experiments with a Native API mode of Windows. Native mode is a mode, where chkdsk starts at the boot time before login screen appears. It is used by chkdsk utility to check and correct errors in the system partition.
　　它一般在bios和系統啟動之間運行，比如，斷電重啟，windows會自動進行磁盤檢測，這個就是Native shell在運行。
