How to set environment variables in Windows 11

Information about the operating system’s environment is stored in Environment Variables. Different settings are required for different programs and processes to run. Windows must ensure that all programs and processes on a single computer have access to the Environments they require. Details such as the operating system path, the number of processors used by the operating system, and the location of temporary files are included in this data. In short, Environment Variables are simply Data Storing Mechanisms. Let us learn how environment variables function and how to properly add, change and delete them in this article.

What are Environment Variables?

An environment variable is a dynamically designated value that can influence how computer processes behave. They store the data and are a component of the process environment. The WINDIR environment variable, for example, specifies the location of the Windows Installation Directory. This value of the variable can be used by programs to determine where Windows Operating System files are stored. Some of the most common and significant Environment variables are PATH, HOMEPATH, and USERNAME in Windows. All these variables store values that any system user or process can access at any time.
In the  Windows command prompt, the user can simply type ” echo%Environment Variable name%”, and in Windows Powershell, the user can simply type ” $Env: Environment variable name”, to know and display the variables.

Setting the Environment Variables


In order to use and set the environment variables, we need to get permission from the system administrator and have privileges. So, you need to inform the system administrator and seek their help if you are not one. After having these privileges follow the steps below to set the Environment Variables.

Step 1: Simultaneously press ” Windows+R” and type ” sysdm.cpl”.

Windows PATH Variable

What is Windows PATH Variable?

The PATH variable is simply an address book of your computer’s programs and commands. You must give the address of any new software on your computer that you want to launch from the command-line interface in the PATH variable.
Windows looks for the address for a certain command as part of the process. When you issue a command from the command line, Windows looks for it in the current directory first. If the operating system cannot locate it in the current directory, it looks for the address in the PATH variable.

How to add to the PATH variable?

Follow the steps given below to modify the PATH on Windows

Step 1: Type ” edit Env “ in the search bar and click on Edit Environment variables for your account.

Step 2: Click on Environment Variables.

NOTE: Along with this, you can also do many more modifications like editing, reordering, or deleting.
Step 5: You may need to RESTART your system so that the changes will be reflected and the system will make sure all apps are running with this PATH change.
Finally, keep in mind that the PATH variable is different for each user in a system. As a result, several users can list different folders without having to change the variable for each one. If you want a tool to be available to all users, you must change the PATH variable in System Variables.
This is all about using Environment Variables in Windows.
