You need to specify the hide parameter for windows.

import subprocess
kwargs = {}
if subprocess.mswindows:
    su = subprocess.STARTUPINFO()
    su.dwFlags |= subprocess.STARTF_USESHOWWINDOW
    su.wShowWindow = subprocess.SW_HIDE
    kwargs['startupinfo'] = su
process = subprocess.Popen( (r'c:\python25\python.exe',
    r'd:\projekte\bar.py'), **kwargs )
