Windows 10 Creators update removed NIC teaming while Intel doesn’t offer teaming support for legacy devices on Windows 10.
But what if I told you, they do?

What do you need?
- Legacy Intel NIC (in my case Intel Pro/1000 PT Quad),
- Windows 10,
- Goats.
Step by Step:
1. Install the latest Windows 10 Drivers for Intel NICs
I used version 24.2 as it was the latest version at the time.
Grab it from here: https://downloadcenter.intel.com/download/25016/Intel-Network-Adapter-Driver-for-Windows-10
2. Install or extract the driver
In my case I could just install the driver normally. If you can’t install the driver, due to the adapter no longer being supported, just extract the archive using WinRAR.
3. Select the wrong driver
All you have to do is choose the wrong driver, that somehow works and magically support teaming.
I choose 217-LM, but 218 and 219 also worked in my testing.
(My NIC is already teamed.)
4. Setup the teaming
I already created the team, but it’s as simple as clicking New Team… 
That’s It, You’re Done!
UPDATE: Windows 10 1909 somewhat broke this method.
Now you need at least one card that supports teaming. But don’t worry you can remove it later.
Create a Team just like before but with a supported card, then remove the card, this will totally crash the manager, so don’t close anything, wait 5 minutes, then reboot.
And wola, it works.
