Downloaded official insider ISO 22000.132, as usual it has the install.wim instead of the install.esd.
To create the FAT32 installation media I had to convert the file manually to stay within the 4GiB size limit for the file.
Why isn't MS putting a little extra effort preparing the ISO with install.esd ?
That would save the aggravation for all insider testers when trying to make the USB FAT32 installation Media..
I've seen other FBH older report for the same issue: https://aka.ms/AAdjk28
