Fix Java Environment Variables Not Updating

If the changes made to the Java environment variables have not taken effect, you can try the following troubleshooting steps:

1. Sometimes, after making changes to the environment variables, it is necessary to restart the computer for the changes to take effect.
2. Check if the environment variables are set correctly: Make sure the installation path for Java is correctly set in the environment variables. You can follow the steps below to check:
3. Open the “Control Panel.”
4. Click on “System and Security”.
5. Click on “System”.
6. Click on “Advanced system settings.”
7. Click on “Environment Variables” in the pop-up dialog box.
8. Locate the variable named “Path” in either “System Variables” or “User Variables”, and make sure that its value contains the installation path of Java.
9. Check for duplicate environment variables: Having multiple Java environment variables may lead to conflicts. Make sure to only set one correct Java environment variable.
10. Check for the impacts of other software: Some software may override or modify the Java environment variables. You can temporarily disable these software or their related features to eliminate interference.
11. Check the firewall and security software: Some firewalls or security software may block changes to environment variables. You can temporarily disable these software to test if the changes can take effect.

If the issue persists after trying the above methods, it may be necessary to further understand specific details such as the operating system and Java version, or attempt to reinstall Java to fix the problem.
