How to manage environment variables in Windows via the graphical interface and terminal?

Environment variables are dynamic named values that affect the behavior of processes and the execution of applications in the Windows operating system. They are used by developers to specify paths to programming language interpreters, compilers, and other system tools, providing global access to necessary utilities from any command-line directory.

To configure environment variables through the classic graphical interface, you need to open the search menu, type the phrase for editing system environment variables, and go to the corresponding section of the system properties. In the window that opens, you should click the environment variables button, where you can see the separation between parameters for the current user and global parameters for the entire operating system.

In the editing window, users can add new paths to the Path variable, change their order, or create their own user variables to configure third-party software settings. It is important to remember that changes to global environment variables may require restarting previously launched terminals or even the entire operating system for the new processes to apply them correctly.

To work with variables through the modern command-line interface, special system parameter management commands are used. Administrators can quickly view current values or change them in automation scripts, which significantly speeds up the initial setup of developer workstations and the deployment of software on new computers.
