Is Windows 10 Software NIC Teaming now possible?
Solution 1
-- EDIT 5/4/16 --
This has been disabled in the most recent version of Windows 10 as well as the insider build 14295. The powershell command will error out or say that LBFO is not supported on the current SKU depending on the versin of Windows you are running. Hopefully MS will re-enable this feature sometime soon.

Yes, This is possible! To anyone else who found this post by Googling:
I haven't found a way to access this though a GUI, but running the following PowerShell command will create a team for you. Just replace the Ethernet names with your NIC names.
New-NetLbfoTeam TheATeam "Ethernet","Ethernet 6"
You should then get a 2GBs Switch Independent team. From there you can use the Network Connections screen to set it up how you want.

It seems this feature is coming back, at least for Intel NICs:
Intel mentions teaming support for Windows 10 in driver versions 22.3 or newer. Currently 23.5 is available.
This version comes with ANS (advanced network services, installed by default) which should allow teaming via powershell commands.
I havent tried it yet - the only mainboard I have with two intel nic's is a bit bios upgrade stubborn.
If anyone could get this to work with the latest windows creator update mentioned in the release notes, let me know :)
Update: tried link aggregation on Windows 10 - so currently it works (Jan 2019)
PS C:\Windows\system32> Import-Module -Name "C:\Program Files\Intel\Wired Networking\IntelNetCmdlets\IntelNetCmdlets"
PS C:\Windows\system32> Get-IntelNetAdapter

An iperf3 run from two clients shows it seems to work:

No it is not possible to get NIC teamin in Windows 10 client SKUs. But available for Server SKUs.
From 14393 version (Anniversary update) this NIC teaming feature had been blocked or removed forever. It is seemed that the feature mistakenly added to client Windows 10 SKUs. When you put New-NetLbfoTeam command in PowerShell e.g. New-NetLbfoTeam -Name "NewTeam" -TeamMembers "Ethernet", "Ethernet2"
, the error shows as follows
New-NetLbfoTeam : The LBFO feature is not currently enabled, or LBFO is not supported on this SKU. At line:1 char:1 + New-NetLbfoTeam -Name "NewTeam" -TeamMembers "Ethernet", "Ethernet2" + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (MSFT_NetLbfoTeam:root/Standa rdCimv2/MSFT_NetLbfoTeam) [New-NetLbfoTeam], CimException + FullyQualifiedErrorId : MI RESULT 1,New-NetLbfoTeam
The main reason was given in Social.TechNet.Microsoft: Nic Teaming broken in build 10586 as follows (quoted):
"There are no native LBFO capabilities on Win10. Microsoft does not support client SKU network teaming.
It was a defect in Windows 10 build 10240 that “New-NetLbfoTeam” wasn’t completely blocked on client SKUs. This was an unintentional bug, not a change in the SKU matrix. All our documentation continued to say that NIC Teaming is exclusively a feature for Server SKUs.
While the powershell cmdlet didn’t outright fail on client, LBFO was in a broken and unsupported state, since the client SKU does not ship the mslbfoprovider.sys kernel driver. That kernel driver contains all the load balancing and failover logic, as well as the LACP state machine. Without that driver, you might get the appearance of a team, but it wouldn’t really do actual teaming logic. We never tested NIC Teaming in a configuration where this kernel driver was missing.
In the 10586 update (“Fall update”) that was released a few months later, “New-NetLbfoTeam” was correctly blocked again.
In the 14393 update (“Anniversary update”), we continued blocking it, but improved the error message."

Windows Server 2012 brought with it NIC teaming of adapters by different manufacturers.
I mean teaming using 1 NIC from say Intel and the other from Realtek. It has been possible to do teaming or bonding at the driver level, but what was introduced in Windows Server 2012 is at the operating system level. I appreciate Linux has been doing this for years :-)
It didn't make it onto Windows 8/8.1. I've seen some article where people reported it was working on Windows 10 Preview but no longer working.
Is NIC Teaming supported on Windows 10 Pro? Or another edition.
-
Admin almost 9 yearsNIC teaming has been possible in Windows since at least Windows XP. What exactly did you read where?
-
Admin almost 9 years@qasdfdsaq at a driver level yes, but you'd need adapters of the same model. I don't mean to say they support a pair of realteks, or a pair of intels. I mean it supports teaming using 1 Intel and 1 Realtek. If you have a suggestion of how I may more clearly define this then please let me know.

Admin almost 9 yearsRealtek is pretty terrible for that. Intel had driver support in windows 8 for my card but you're really better off with a second intel, even if you have 'support'. I never quite got it working with a realtek

albal over 8 yearsThank you very much @FunkeDope - I added a screenshot to your post. Works perfectly. Now I will have to do teaming on my VM Server ;-)
-
Bilo over 8 yearsOnce I have created the teaming, how can I remove it? The remove button is greyed out when I right click the team interface.

Nate over 8 yearsNote your PowerShell session will need to be running as and administrator
-
Cocowalla over 5 yearsAny idea about non-Intel adapters, such as Realtek?
-
wemu over 5 yearssince this feature comes from the intel driver I assume its the same for realtek: only if their driver supports it
-
user7424603 about 4 yearsIt worked with intel and tp-link cards

Polynomial about 4 yearsI have come up with a way to re-enable LBFO on Windows 10 by extracting files and registry keys from a Windows Server ISO. See my answer for details.

Greg Woods almost 4 yearsAfter spending most part of the day trying to team a dual Intel card.. without success, I recognised immediately that this answer is Intel specific. You should make that clear from the beginning of your answer.
