How do I set Windows Environment variables permanently? [closed]

Question

How do I set Windows Environment variables permanently, I see that the Windows environment variables are reset when you close the command window. I want to set them permanently so that I don't have to repeat the task every time I use CLI.

Answer 1

Right click on Computer, Advanced system settings, select Advanced tab and click Environment variables.

Note: once you modify the environment variables, you will have to restart your applications, including CLI.

Answer 2

This can also be achieved from command prompt. The following example set a variable at user level:

SETX variable_name value

For machine level elevation is required:

SETX variable_name value /m
