Received new Surface Pro 4 with Windows 10 Pro installed - I7, 256GB drive, 16GB memory. Upgraded to Win 10 Enterprise by using Enterprise Key. Ran latest MS driver/firmware updates on system after upgrading to Win 10 Enterprise. Ran ALL Windows 10 Updates. Three Firmware devices in device manager are showing Yellow Triangles and state Operation Failed - This device cannot start. System also appears to be running slower than I would expect. Even if I try to manually update them, message Best driver is already installed. I am logged on as administrator of this system. I cannot deploy this system until this is resolved. Any thoughts?
