I looked at my setup as we upgraded from 5.3 to 6 recently this year, and my network adapters look fine.

Few things with my setup though:

Network Adapter is E1000 (your screenshot shows the VMXNET3)

We are disabling IPv6 via GPO:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters]

"DisabledComponents"=dword:ffffffff

I'm thinking your problem is related to the VMXNET3 network adapter and a VM Tools update.
