主要原理是，通过函数creation_flags设置CreateProcess函数的creation flags，设置为 隐藏窗口即可。

关键命令：

![windows_subsystem = "windows"]

use std::os::windows::process::CommandExt;

.creation_flags(0x08000000)

#![windows_subsystem = "windows"]
use std::process::Command;
use std::os::windows::process::CommandExt;

fn main() {

    let output = if cfg!(target_os = "windows") {
        Command::new("cmd")
                .creation_flags(0x08000000)
                .arg("/C")
                .arg("rundll32 sysdm.cpl,EditEnvironmentVariables")
                .output()
                .expect("failed to execute process")
    } else {
        Command::new("sh")
                .arg("-c")
                .arg("echo hello")
                .output()
                .expect("failed to execute process")
    };
    
    let hello = output.stdout;
    println!("{:?}", hello)
}
