Why Environment Variables Matter

• PATH helps Windows locate executable files.
• TEMP and TMP store temporary data.
• USERPROFILE directs apps to your user folder.
• Developers use them to configure Java, Python, or Node.js runtimes.

Incorrect editing can break app behavior, so modify with caution.

What Are Environment Variables in Windows?

Environment variables are key-value pairs that store system settings and user preferences. For example, the PATH variable tells Windows where to find executable files, while TEMP defines where temporary files are stored.

They can be system-wide (apply to all users) or user-specific (apply only to your account).
