Microsoft DOS break command
Break can be used to enable or disable the breaking capability of the computer. For example, if a user wanted to cancel a batch file or another MS-DOS processes, that user could press CTRL + C (break), which would then prompt the user if they want to cancel the current process.
Turning break off will cancel CTRL + C; however, the user will still be able to press CTRL + PAUSE/BREAK and have the capability of getting out of a batch file or current running process.
Note: Newer versions of Windows (Windows ME, Windows 2000, Windows XP, and higher) only include this command for backwards compatibility and turning the break off has no effect.
The break command is an internal command and is available in the below Microsoft operating systems.
