GPO for adding reg key on win 10 systems

Hi,

I'm trying to create a GPO that will allow me to add a folder & reg key inside that only restricted for Win 10 using GPO. I used the command on command prompt and it works as expected but I want it to be achieved using GPO how can I do it?

here is command that I used.

reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade /f /v AllowKMSUpgrade /t REG_DWORD /d 1

Below is the image of what i'm trying but it's now working. I've also applied WMI for Win 10 filtering.
