Why does my php command in CLI return empty line?

问题

When I'm writing a php -f program.php command in my CLI, i get no response.

I have tried to write php -h command or php -r 'echo 'try' command or php -i command and I still get no response.

Enviroment variables is properly set but problem occurs even if I'm in xampp/php/ directory.

Php in my applications works, problems occurs only in CLI.

Problem starts probably after my windows update. Anyone can help me please?
