vCenter operations produce login to the query service failed an ssl error occurred message

Once logged into vCenter managment console and trying to do operations like look at performance stats or sort the virtual machine list I received this message "login to the query service failed an ssl error occurred"

I found a quick an easy fix at https://communities.vmware.com/thread/538636?start=0&tstart=0

It seems that a microsoft update removed some Security Key Exchange Algorithms.

Here was the quick fix.  Basically add this registry entry and you're back in business:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\KeyExchangeAlgorithms\Diffie-Hellman]
"ClientMinKeyBitLength"=dword:00000200
