[python-win32] Issuing a command via subprocess, other methods in Windows 7

[Preston Landers]

I thought "start" wasn't an actual executable but rather a builtin
command of the cmd.exe shell.

Have you tried something like:

scope = subprocess.Popen([r'cmd.exe', '/c start SoundRecorder'],shell
= True, stdout=subprocess.PIPE)

regards,
Preston
