The bootcfg command is used to build, modify, or view the contents of the boot.ini file, a hidden file that is used to identify in what folder, on which partition, and on which hard drive Windows is located.
The bootcfg command was replaced by the bcdedit command beginning in Windows Vista. Bootcfg is still available in Windows 7 but it serves no real value since boot.ini is not used.
The bootsect command is used to configure the master boot code to one compatible with Windows 7 (BOOTMGR).
The bootsect command is only available from the Command Prompt in System Recovery Options.
The break command sets or clears extended CTRL+C checking on DOS systems.
The break command is available in Windows 7 to provide compatibility with MS-DOS files but it has no effect in Windows 7 itself.
CaclsThe cacls command is used to display or change access control lists of files.
Even though the cacls command is available in Windows 7, it's being phased out. Microsoft recommends that you use the icacls command instead.
The call command is used to run a script or batch program from within another script or batch program.
The call command has no effect outside of a script or batch file. In other words, running the call command at the Command Prompt will do nothing.
