Speaking of PATH, here is a wad of code I wrote to add a path in Win. If such
a
thing already exists, I couldn't find it.
pretty much the 2 key lines are:
SetValueEx(h, 'path', 0, REG_EXPAND_SZ, NewPath )
rc, dwReturnValue = win32gui.SendMessageTimeout(win32con.HWND_BROADCAST,....
Add it to the reg, use it now (otherwise it doesn't get used till you reboot.)

# addtopath.py
"""
Adds the passed parameter to the windows PATH
Checks to make sure the dir exists and is not already in the path.

import sys
import os
from _winreg import *
import win32gui, win32con
if len(sys.argv)==1:
# add the python dir to the path
DirToAdd = os.path.dirname( sys.executable )
else:
DirToAdd = os.path.abspath(sys.argv[1])
if not os.path.exists(DirToAdd):
print "dir %s does not exist." % DirToAdd
sys.exit(1)
hive = HKEY_LOCAL_MACHINE
key=r"SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
subkey = 'Path'
h = OpenKeyEx( hive, key, 0, KEY_READ )
curPath = QueryValueEx(h, subkey)[0]
CloseKey(h)
if DirToAdd in curPath.split(';'):
print "dir %s already in current path:" % DirToAdd
print curPath
sys.exit(2)
print "adding dir %s" % DirToAdd
h = OpenKeyEx( hive, key, 0, KEY_SET_VALUE )
NewPath = curPath + ';' + DirToAdd
SetValueEx(h, 'path', 0, REG_EXPAND_SZ, NewPath )
CloseKey(h)
print "Path set to", NewPath
rc, dwReturnValue = win32gui.SendMessageTimeout(win32con.HWND_BROADCAST,
win32con.WM_SETTINGCHANGE, 0, "Environment", win32con.SMTO_ABORTIFHUNG,
5000)
sys.exit(0)
