How do I troubleshoot environment variables in Windows?

To troubleshoot environment variables in Windows, you can start by checking the current variables set in your system. You can do this by opening the Command Prompt and typing set to see all environment variables.

What if I can't find the variable I'm looking for?

If you can't find the variable, you may need to create it. You can do this by going to System Properties > Advanced > Environment Variables, and then adding a new variable under either User or System variables.

How do I know if the variable is set correctly?

You can verify if the variable is set correctly by reopening the Command Prompt and typing echo %VARIABLE_NAME%, replacing VARIABLE_NAME with the name of your variable. If it returns the expected value, it's set correctly.

What should I do if the variable still doesn't work?

If the variable still doesn't work, ensure that the application using it is restarted, as changes to environment variables may not take effect until a new instance of the application is launched.
