2 external monitors with bootcamp and windows 7, worked but not now - confused

Hello,

I truthfully don't have a clue how you managed to get it working in the first place.
We have never supported bootcamp on that version of Windows because the layer of virtualisation makes accessing the device in a low level manner unreliable or mostly impossible.

That has changed with Windows 10 Anniversary Update as we do not need to have kernel mode drivers as DisplayLink USB graphics support is natively built into the OS. We only need to and only have a user mode device driver there.

Kind regards,
Alban
