The new 1809 (RS5) Windows 10 release is causing some issues with the RGB utility, on the previous 1803 (RS4) it seems to work fine.

Note, this only applies to boards with Addressable RGB, so:
B450; X470; Z370 and Z390


The cause is the new Windows 10 release, and the use of the Windows powershell to execute some commands.

When the utility is installed it extracts a number of files to the C: drive

Her is how to solve it

1.       Download the latest 1.0.26 utility:

2.       Uninstall the RGB Led utility and reboot

3.       Install the 1.0.26 utility and reboot

4.       Start the utility, it will detect the RGB hardware, (it should also install the firmware update, and that is what goes wrong in the latest Windows version, it doesn't update!)

5.       Now we have to manually update the firmware via the command prompt

6.       Open the Command Prompt (Windows key+r and type in cmd and click okay)

7.       Type (or copy/paste);
Quote cd C:\Program Files (x86)\ASRock Utility\ASRRGBLED\Bin
then press enter

8.       Type DIR, and check for 2 files wicpflashadsb.exe and nu51_2.07 (this is the latest firmware)

9.      Type; wICPFLASHADSB.exe /File=FilenameHere example:
Quote wICPFLASHADSB.exe /File=nu51_2.07
Quote wICPFLASHadsbv2.exe /File=nu51_2.07
on newer versions
10.   Press Enter, the firmware for the LED controller will be reflashed

11.   Done

This is a known issue and a proper fix is in development. For now, you can either hold off on installing/updating the RGB utility and wait for a fix or you can use this workaround to get things working correctly.

This info was provided by my contact at ASRock who requested I share it here for you all.
