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

<code>
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
</code>


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.
