How to edit environment variables in Windows 10

Environment variables are values that contain all the information regarding the system environment. Every process within the Windows OS has a block that contains a set of environment variables and their values. There are two kinds of environment variables, namely User Environment Variables and System Environment Variables. As the name suggests, user environment variables are set for each user, while system environment variables apply to everyone using the system.

Any user working with the command prompt or batch scripts will be well aware of environment variables due to the repetition of values. Every environment variable has two parameters: name and value. Therefore, you can edit or create your own environment variables to make your work easier. In this guide, I will discuss the ways to edit environment variables in Windows 10.
