How to Set Environment Variables in Windows

Setting environment variables in Windows is like giving your computer a set of instructions to follow. It’s a way to tell your system where to find certain files or how to behave when running programs. To do this, you need to access the system settings, add your variable name and value, then save the changes. With just a few clicks, you’ll have everything running smoothly.
