How to add an environment variable in Windows 10

What is an environment variable?

Windows has a number of different built-in environment variables for opening folders, folders, and running processes. Some built-in variables include TEMP, userprofile, windir, prefetch , .

How do environment variables in Windows work?

In fact, Windows even creates some custom environment variables for its own applications. For example, to open the OneDrive folder, you can simply execute the "OneDrive" command in the Run window. This happened because OneDrive created a new environment variable in the background.

If you have a directory or process that you want to open with a dynamic value, you can add an environment variable for that value. For example, you have a custom variable to open the Downloads folder . This makes it easy to access the folder in custom scripts and other applications. You don't have to worry about the actual directory location as long as it is properly configured in the environment variable.

Here are the steps to add an environment variable in Windows 10.
