Windows 10 Enterprise v1709 also has support for 4 sockets.
Windows 10 Pro for Workstations is being talked up to allow individuals like myself to use high end hardware for workstation type tasks. I have been waiting for this for years now and in the interim have become quite versed in Linux and Windows Server due to my requirement to use 4 sockets on the Poweredge systems I have.
Interestingly enough, it would appear that as of version 1709 Windows 10 Enterprise also has support for 4 sockets. This is excellent news for anyone that does heavy processing in an enterprise environment. I for one am ecstatic to see my system running Windows 10, having proper support for GPUs and supporting 4 sockets.
