Windows IP settings from old Windows network adapters after card replacement Rumi, July 25, 2022 After replacing an old motherboard with a new one, the NIC is different, has a new MAC address and generally needs a new TCP/IP configuration. However the old NIC is still somewhere there with its designated IP address and the rest. Question: is it possible to retrieve those settings (most important is the static IP address) for an old network card that is no longer present in the system? Solution: Open run and type regedit Browse- [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces] You’ll find your card and their configuration settings.
