Thanks for the update Carl.
I updated a few of my machines to the latest build of Windows 10 today - Version 1522 Build 10586.3 ... and it broke my working Team.
For some reason the "Upgrade" process replaced some of my drivers with the Microsoft Inbox versions ! Once I'd got my Intel RST and Intel ProSet and Creative Audio drivers installed again, I got the teaming options back in Device Manager.
But after creating a Team, it only shows in Device Manager - it does not show in Network and Sharing Centre (ie, Windows 10 doesn't even recognise it as a network device). So no Teams at all now.
I'll also point out that Windows 10 replacing my Network drivers left me with ZERO connectivity until I reinstalled ProSet - so if you're doing this on a Remote machine, you'll be screwed after the upgrade completes.
