Windows7 run python script / sub process with elevated privileges

[News123]

Hi,

I have a small python script, which has been started as normal non
privileged user.

At a later point in time it would like to start another python script
with elevated privileges.

How can I write my code such, that I will get the privilege elevation
prompt and I can start a sub process / python function with elevated
privileges.

thanks for any hints.

Under Linux Ubuntu I would use sudo/gksu

Under Windows 7 I'm a little lost.

A Python only solution is of course prefered, but any .bat .c .C# .cmd
wrapper would be fine.

I Found a first solution, though not very satisfying:

wrapper would be fine.

I could call following command:

PowerShell -Command (New-Object -com
'Shell.Application').ShellExecute('Cmd.exe', '/c
c:\abs_path_to_my_app\pyscript.pyw', '
', 'runas')


So I might do something like:

# ########### script starts
import subprocess

cmd_wrap = "PowerShell -Command (New-Object -com "\
"'Shell.Application').ShellExecute('Cmd.exe', "\
"'/c %s', '', 'runas')"

args = r"c:\abspathtommyapp\myapp.pyw"

cmd = cmd_wrap % args

# create KW args to hide console
kwargs = { }
su = subprocess.STARTUPINFO()
su.dwFlags |= subprocess.STARTF_USESHOWWINDOW
su.wShowWindow = subprocess.SW_HIDE
kwargs['startupinfo'] = su
p = subprocess.Popen( cmd.split() , **kwargs )
# script ends here


However my issue is, that I have one annoying console window popping up
when PowerShell starts cmd.exe


Is there anything better?

The canonical way is to use the "runas" verb from within
ShellExecuteEx, which is exposed by the win32api module.
