I'm installing Remote Utilities Host on a Windows 10 computer and am getting an alert that the monitor driver is unsigned. In device manager, the PnP-Monitor Lock (Standard) device has an explanation point showing its an unsigned driver. I've installed the host on Windows 10 in the past and not had this issue.
Then it's either an outdated root certificate or intermediate certificate problem. As an example, here is how the monitor driver properties window looks now on our test PC, RU version 188.8.131.52 downloaded from the site.
Having rebooted, Device Manager indicates that the driver is disabled because it's signature can't be verified. Displaying the driver details shows "Remote Utilities LLC" as the signer (as in the screen shot above), so the question is: what certs need installing to make this work???
After some investigation we found that it's not actually the driver or root drivers to blame. It's Microsoft's new policy that was put in effect after one of Windows updates. Now they require additional verification in their Dev Center (us as a vendor).
We went through all the necessary procedures and the changes we submitted are currently pending.
