I am using GetAdaptersInfo() to READ the NIC's Description and using it. However, I recently came to know that, someone can modify this in Windows Registry, as there is a key called Friendly Name in HKLM tree section.
For me it is somewhere in Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\ROOT...
My problem is, not to get into this problem and get the Description field which in not impacted by change in Friendly Name field.
