Whenever I try to run the LED Manager in Windows 10 Home, I get an error: "Error getting the status of the LEDs." I have version 126.96.36.19974 of LED Manager, I've run the Intel Support Assistant and everything is up to date, including the BIOS (default settings except for RAID configuration).
The latest version on LED Manager is ver 1.2.2 : https://downloadcenter.intel.com/download/27641/NUCs-LED-Manager-for-Intel-NUC?product=126143 . So, better update this application. Before using it, ensure that in the bios setting, Software LED Control Enabled field is checked.
