Ugh, I totally misread that section thinking that would remove only the LCU and not the SSU.
However, I tried running the DISM /online /Remove-Package as instructed, but I get an error saying the Permanent package cannot be uninstalled in the logs. I'm using the PackageName options as I don't know the path to the CAB file. Would that make a difference? Is there a CAB file somewhere?
Thank you for the help.
