Different programs and processes require different environments to run. On a single machine, Windows needs to make sure that all programs and processes can access the environments they need. To do this, Windows needs to know the kind of environment every program requires to work.
Windows must store this information somewhere for easier retrieval. Environment variables make that possible. Environment variables are dynamic variables that store data related to creating different environments for different programs and processes. To understand them better, let us take the example of a program that needs to use a built-in Windows tool to run. For the program to use the tool, the program needs to know the tool's location to access it. The program also needs to find out if it has permission to use the tool or not.
Similarly, there are things that a program needs to know before it can use the tool. So, a program can access all of this information by asking Windows. Windows then looks up environment variables EVs for this data and creates an environment in which that program can run. In other words, EVs store data that is accessible to every program and process running on the system across all users.
The data these variables store helps the programs run in the environment they were designed for. All of these variables contain values that any user and process of the system can access at any time. Windows can look up this variable whenever it needs to find out the name of the current user. First things first, if you want to set system-wide EVs, you need to have administrative privileges. So, if you are not the admin, inform your system administrator and ask for their help.
The EVs panel lists two types of variables depending upon your need. On the contrary, if you want system-wide changes, you will change System variables. To do this:. To edit different environment variables, select any variable from the list.
Then, press Edit. This will open up the Edit environment variable panel. Here you can create, delete, and edit variables. From the list of variables, select the one that you want to modify and click on Edit. Afterward, you can change the variable value to anything you like. In simple terms, the PATH variable is an address book of programs and commands on your computer. Whenever you have a new program on your computer that you want to run from the command line interface, you must specify its address in the PATH variable.
A thing to remember here, not all programs are in the PATH environment variable. Only the programs that are meant to be used from the command line interface appear in the PATH variable. The way the process works involves Windows looking up the address for a certain command. Whenever you issue a command on a command line, Windows first searches the current directory for the command. To enter an address in the PATH variable, the process is the same as before. One final thing to remember, the PATH variable is not the same for every user on a system.
So different users can list different directories without changing the variable for every user. Programs need data to work. To make sure that data is available efficiently, Windows stores this data in global variables that all programs can access.
These global variables are Environment Variables. Furthermore, if you have more than one user on a machine, user Environment Variables will be different for each user. On the other hand, system EVs are available for all users. These variables require admin privileges to edit or delete. So, be sure you know what you are doing before modifying them.
