3.1 and 3.11 were far different than the 0.01 would suggest.
* "Standard mode" was dropped, so 3.11 required a 386 or above
* Significant networking improvements (hence the "for workgroups" in the name) including IIRC built-in TCP/IP support (prior to that most people used Trumpet Windsock)
* I/O subsystem improvements too
I've heard it said that WfW3.11 was essentially a huge gamma-test for the network and I/O subsystems intended for what became Windows 95.
There was a non WfW 3.11 though that I think didn't include VSHARE.386; by the time 3.11 was around I think I had my 386/40
Also, WfW did not initially ship with built in winsock implementation, WfW did ship all the networking apparatuses other than that, just needing a drop-in winsock.
