The history of the Windows TCP/IP stack went most likely like this:
IBM (NetBEUI, no TCP/IP) -> Spider TCP/IP Stack + SysV STREAMS environment -> MS rewrite 1 (early NT, Winsock instead of STREAMS) -> MS rewrite 2 (make win2000 faster):

It's interesting how STREAMS pervaded everything for a short while (Apple's Open Transport networking stack for System 7.5 and up was also based on STREAMS) but everyone almost immediately wanted to get rid of it and just use Berkley sockets interfaces.
I still don't quite get how you should had communicate with the other systems over the network with STREAMS.
With IP you have an address and the means to route the data to that address and back, with TCP/UDP sockets you have the address:port endpoint so the recipient doesn't need to pass a received packet to the all processes on the system, asking "is that yours".
So if there is already some network stack providing both the addressing and the messaging...
Berkeley, for disambiguation.
