For this article, we will be talking about ‘Environment Variables’, which is defined as the paths and values that point the OS to important locations when there is a need to save files or access relevant information about the system. The Path Variable is a subset of Environment Variables which points the system to EXE files. Adding a path to an EXE file allows users to have access to it from anywhere without having to switch to the actual directory. The Path Environment Variables in Windows 10 works by adding any path that you like and there are no restrictions to which drive or folder the EXE should be in. You have to have administrative rights to add a Path variable.
Path Environment Variables
Open Control Panel and go to System and Security>System. Alternatively, just type the following in the address bar in File Explorer. Now, this will take you to a certain screen where you have to click the Advanced System Settings.
On the System Properties screen, go to the Advanced tab. Click the Environment Variables button at the very bottom. On the Environment Variables window, select Path from the User variables section and click Edit.
On the Edit Environment variable window, you must click the new button. This will add a new field inside the list of paths. Once it is active, click the Browse button and navigate the folder where the EXE that you want to add to Path environment variables is. Click ok then you are done.
When you add an EXE path as an environment variable, you can access the program from any command line. The command line in Windows being the Command Prompt, you can open a Command Prompt in any location and run commands. Which paths you add is entirely up to you since you know which programs you need to access from the Command Prompt.
