Known issues and additional information about Surface Pro 4; How to get the update. Surface updates are released in stages – not every Surface will receive the update at the same time, but it’ll be delivered to all devices. In some circumstances, you may also see a 'View optional updates' link in the Windows Update settings. Hmm, someone more knowledgeable may know why there's two on my SP3 running win 10 there's HID keyboard and Surface type cover filter device but I'm running a SP4 typecover now. If it were me I'd be tempted to try updating both drivers first, then if that didn't work I'd remove both then reattach the keyboard and reinstall.
