Loaded config file: (none) & # 8594; How to fix it? (PHP)

I have been using PHP on Windows since two weeks. So far, I haven't had any problems. But now I need to change something in my "php.ini" and I cannot do that because no file is loaded as a config file.

If I find "php -ini" in my cmd I get the following response.

    Configuration File (php.ini) Path: C:\WINDOWS
    Loaded Configuration File:         (none)
    Scan for additional .ini files in: (none)
    Additional .ini files parsed:      (none)

      

        
        
        
      

    

I've already read some other questions on this topic, but all the answers didn't work for me. I have a directory "c: / php" with a php.ini file. I tried to copy it to "c: / windows" and restarted apache but nothing changed.

I really hope someone can help me. Thank you.
