[python-win32] Vista, _winreg and "Access denied"

[le dahut]

To complete this, the application is launched at logon (via Userinit 
registry key). It rewrites paths to StartMenu and Desktop according to 
the type of logon (Domain or Local).
Actually it only rewrites when it is a local session and user IsAnAdmin. 
The application as to re-run itself using ShellExecute so it has to know 
if it already runs elevated or not.

To do this I must use :
GetTokenInformation(
                     hToken,
                     TokenElevationType
		    )

Unfortunately win32security.TokenElevationType (18) is not available. 
And GetTokenInformation(hToken, 18) returns
 >>> win32security.GetTokenInformation(hToken, 18)
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
pywintypes.error: (87, 'GetTokenInformation - size call', 'The parameter 
is incorrect')


Is it possible to do this using ctypes ? How ?
