I installed Secure Lockdown Standard in WIN10 and all running well
until i needed to change keyboard, at this moment windows not recognize
keyboard nor mice. I received an message from UAC saying the system cannot
install the device. What i do?
Ps: Keyboard and mice works well in another computer without secure lockdown installed.

Windows User Account Control (UAC) should be disabled.
Disable it, reboot and try again
