[python-win32] gpedit reload method in python

[le dahut]

Hello,

"gpedit.msc" can change several parameters in system for example items 
in start menu or hidden drives in explorer. The changes made in "gpedit" 
are immediately applied, if you have "My computer" opened you can see 
selected letters disappear.
I know that "gpedit" modifies 
HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\NoDrives.
But I don't know how "gpedit" updates the system, what sort of system 
call is done.

I've already tried :
  win32gui.SendMessage(win32con.HWND_BROADCAST, 
win32con.WM_SETTINGCHANGE, 0, 'Environment')
and the commande :
  RunDll32.exe USER32.DLL,UpdatePerUserSystemParameters ,1 ,True
without success.

Does someone know more about this ?
Are there other API calls that update the system ?
