Batch files (BAT) are files that execute on a Windows computer and process plain text commands. Batch files are typically used to change configurations of a computer on a network. One type of administration process used in batch files is a password change, which is executed to prompt the user to change a password during login. Batch files run in the Windows command prompt, so these prompt commands are used in the file.
