Strange. I did test it before I posted. Ah; I forgot that the released version of WMI doesn't allow for positional parameters. Sorry. You can either: 1) Pull the latest release from here: http://timgolden.me.uk/python/downloads/wmi-1.3.2.zip and run again. or 2) Change to the following (notice the named params): result, profile = registry.GetExpandedStringValue ( hDefKey=winreg.HKEYLOCALMACHINE, sSubKeyName=profileskey + "\" + sid, sValueName="ProfileImagePath" )

I must report that, on my AD-attached machine, the Win32UserAccount query above is not fast. You might well be better off following Mark Hammond's suggestion of using win32security: import win32security usersid = win32security.ConvertSidToStringSid ( win32security.LookupAccountName(None, USERNAME)[0] ) and using whatever registry-query module you find most convenient -- there are a bunch of registry-wrappers out there. I wouldn't bother using WMI just for that. TJG

Ok, this is what I've done. Surely not nice to watch but it seems to work:

import _winreg import win32security

username = 'Administrator' sid = win32security.ConvertSidToStringSid( win32security.LookupAccountName(None, username)[0] ) key = _winreg.OpenKey( _winreg.HKEY_LOCAL_MACHINE, r"SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList" + "\" + sid ) value, type = _winreg.QueryValueEx(key, "ProfileImagePath") print value

What I find very strange is that there's no API for doing such a thing in better/nicer ways. Anyway, thanks a lot for your precious help.
