Here is the reply I received from Intel Support:
This is on regards of service ticket 184630.
In order for you to get teamning working you will need to get Intel(R)Advanced network services
set up with the operating system but Windows(R) 10 is not supported for this feature.
Creating Intel® ANS teams and VLANs on Microsoft Windows® 10 is currently not supported.
As a result, when created, teams and VLANs do not pass traffic.
We expect that ANS will be supported on Microsoft Windows 10 client in a future release
The future releases will require modifications from Microsoft in the O.S, unfurntately
it is not possible for us to provide an ETA.
We will not be able why it worked before since we are not Microsoft support we will not have the information
about the previous update you installed.
In this case we may suggest you to contact Microsoft support to check if they have another solution available
since their update was taking that feature away and and from us Intel this feature will not be supported on your
operating system.
Please let us know if further assistance is required and/or if we can proceed to close this service ticket.
We will be waiting for your response.
Have a great day!
