Help $OEM$

[ToysILike]

I know this is an old thread. But since I came hear to search the same issue and didn't fine much, here's my take: $OEM$ used to work for me back when I was putting autounattend.xml files in the root of the Windows ISO. But ever since I started using a Ventoy .xml template folder for different .xml configurations, $OEM$ doesn't work anymore. I suggest creating a "setup" folder in the Windows folder in install.wim and put your setup scripts there, since they are copied to that location from the $OEM$ folder.
