How to edit environment variables in Windows 10

Environment variables are the values that contain all the information regarding system environment. Every process inside Windows OS has a block that contains a set of environment variables and their values. There are two kinds of environment variables i.e. User Environment Variables and System Environment Variables. As the name represents, user environment variables are set for every user while system environment variables are for everyone who uses the system.

Any user working on command prompt or batch scripts will be well aware of environment variables because of the repetition of a value again and again. Every environment variable has two parameters i.e. name and value. So, you can edit or create your own environment variables in order to ease the work for yourself.
