Fixlet to change channel of Office365 from Broad to Monthly not working

Hi,
I would like to inform you that the fixlet 365039 doesn’t work. The registry key is correctly edited but even after the reboot, the channel remains “Broad”. I developed this fixlet that works:

waithidden cmd.exe /C “C:\Program Files\Common Files\Microsoft Shared\ClickToRun\OfficeC2RClient.exe” /changesetting Channel=Monthly

Best regards
Marco
