setx

setx is a command-line tool in Microsoft Windows used to set environment variables permanently. It allows users to modify, create, or delete environment variables from the command prompt or batch files. The setx command replaces the older set command and has more advanced features. With setx, users can set both system-wide and user-specific environment variables. The command syntax includes the variable name, the value to assign to the variable, and an optional parameter to specify whether the variable should be set in the user or system environment. By default, setx sets the variable in the user environment unless specified otherwise. Additionally, setx can read from a file and set the variable value accordingly, making it convenient for automated configurations.
