I suspect the Windows 10 guest does not see the NUMA architecture but just sees the two virtual sockets.
What does the Task Manager - set affinity show in the Windows 10 guest show?
On a dual socket CPU physical machine, Windows 10 Pro the set affinity from Task Manager shows this picture
A Windows 10 Pro VM running inside VMware Workstation 16 beta on the same physical machine as above, configured with 2 virtual sockets with 4 cores each, the set affinity shows this picture
The physical Windows 10 Pro shows the node 0 and node 1 while the Windows 10 Pro VM does not, although the Windows 10 Pro VM sees 2 sockets.
