Hi,
We are aware of the issue, background is basically Windows 10 had "softly" stopped unsigned drivers being used but it wasn't being enforced. However in there latest update:
"Windows 10, version 1607, the operating system will refuse to load any new kernel mode drivers that are not signed by the Windows Hardware Developer Center Dashboard portal, or Dev Portal. To be clear, new installations of this version of Windows 10 will enforce the new driver signing rule, whereas older versions of Windows 10 upgrading to 1607 will not be affected by the change"
This has only recently been announced and has caught many hardware developers out of the blue.
We will be getting the drivers certified and will keep everyone up to date on the progress. Apologies for the inconvenience caused.
