How does the Command::new API hide the window of the calling program on Windows?

Question

For example, I get the result of Query User by calling powershell.exe:

let output = Command::new("powershell.exe")
    .arg("Query")
    .arg("User")
    .output()?;

// Parse the output in std... 

Unfortunately, doing so will bring up a powershell window (although it will soon disappear).

Is there a way to call the console program without displaying any windows?
