If you see “windows sockets registry entries required for network connectivity are missing”, it seems that the actual registry entries are possibly corrupt. This may have affected TCP/IP. You need to know, this is considered a manual winsock reset of sorts, and involves modifying the registry. You must backup the full registry before you ever touch it. Also backup/export keys that you are intending to modify or delete. So the main goal is to use the registry editor to delete the winsock then remove and reinstall TCP/IP on Windows. OK to do this, follow these steps on windows 10.
