[BangPypers] Execute Windows "shutdown" command through python !

[Yuvi Panda]

Okay, the problem seems to be the fact that you're calling shutdown.exe from
a 32 bit process (I presume you're using the more popular 32 bit version of
python, rather than the native 64 bit one).

Under 64bit windows, any call to a system32/* executable from a 32-bit
process is silently redirected to syswow64\*, which contains 32 bit versions
of (almost) all the executables. So when you call system32\shutdown.exe from
your python process, Windows tries to call syswow64\shutdown.exe.

Problem is, there is *no* 32bit version of shutdown available
(syswow64\shutdown.exe doesn't exist), so your call ends up failing.

tl;dr version - You can't call shutdown.exe on a 64 bit machine from 32 bit
python

Solutions:
1. Use the native 64 bit version of python
2.
