In this article, we will explore the usage of setx.exe in Windows 11. Setx.exe is a command-line tool that allows users to set environment variables in the Windows operating system. Environment variables are dynamic values that can affect the behavior of various programs and scripts running on the system. Understanding how to use setx.exe can be beneficial for system administrators, developers, and power users who want to customize their Windows environment.

Examples:
1. To set a new environment variable using setx.exe, open the Command Prompt or PowerShell and use the following syntax:

setx VARIABLE_NAME "VALUE"

For example, to set a variable named "MY_VAR" with the value "Hello, World!", you would run:

setx MY_VAR "Hello, World!"

After running this command, the variable will be available for use in any subsequent command prompt or PowerShell session.

2. To modify an existing environment variable using setx.exe, you can use the same syntax as above. For example, to change the value of the "MY_VAR" variable to "Goodbye, World!", you would run:

setx MY_VAR "Goodbye, World!"

This will update the value of the variable, and any programs or scripts that rely on it will use the new value.

3. To delete an environment variable using setx.exe, you can use the following syntax:

setx VARIABLE_NAME ""

For example, to delete the "MY_VAR" variable, you would run:

setx MY_VAR ""

After running this command, the variable will be removed from the system.
