Thank you, this will help me. I'll try it later. Remote shutdown and restart for me is allready solved. I used server-client, where user send request to shutdown in type of some message eg. "Shutdown-123". Other pc will receive the message and by request it will start command in cmd (all in background > "shutdown -s -f" / "shutdown -r -f"). It's lightway solution which didn't need admin permision. Once again thank you for WOL.
