如何在后台启动应用程序,即不显示GUI？

start /B notepad.exe

firefox &

import subprocess
import sys

if sys.platform.startswith('win'):
    startupinfo = subprocess.STARTUPINFO()
    startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
    subprocess.Popen(["notepad.exe"], startupinfo=startupinfo)
else:
    subprocess.Popen(["firefox"], stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL)

import subprocess
import time
from pygetwindow import getWindowsWithTitle, getWindow

subprocess.Popen("notepad.exe")
time.sleep(1)
window = getWindow(title="Untitled - Notepad")
window.hide()
