Ok, I have downloaded the hotfix. The setup says that the hotfix is
not meant for my version of Windows and quits. So, just for the sake of
it, I've hacked into the hotfix and extracted the iphlpapi.dll, and I've
modified c-ares to LoadLibrary("C:\\new\\iphlapi.dll"). It seems to
work. No more leaked handles and the nameserver information returned by
GetNetworkParams is right.
But I wouldn't go as far as installing the new dll to
C:\Windows\System32. That seems risky. However, a new hacky alternative
has sprung: we could distribute the 'fixed' iphlpapi.dll into c-ares and
LoadLibrary() it. But I am sure that the Microsoft EULA forbids that.
