Dear friend, I saw in your code that you use "Create ISO with install.wim", "Add Updates (internally)", CleanUp, ResetBase, and NetFx3 (Framework 3.5). That resulted in a ISO file with 5785305088 bytes = 5.39 GB Sometimes I use "StartVirtual" option with "AutoEditions" left empty to have all the editions (in Windows 10), having exactly the same option as you (except AutoStart=2 – ISO with install.esd). But if I enable "StartVirtual" option (generating All Editions) will the (final) ISO file be increased (bigger size)??? I think it doesn't because they are only "Virtual" Editions, they have no "size", maybe I'm wrong.
It will increase only by a bit, as only one full index is kept, with the other ones only storing the changes to the first one. So, only actual differences between SKUs will increase the size, should be only a few hundred MB.
Thanks for your response, dear Carlos. I didn't get notified of your reply because you didn't quote me. Don't worry Interesting, I thought the size increasing was only a few megabytes (maximum 50 MB). So, having UUP of Pro Edition, and letting the Script to creating all the extra six editions (ProEnt, ProEdu, ProWorkstation, ServerRdsh, IoTEnt, Edu), maybe the difference would be aprox. 500 MB. Dear @abbodi1406 is it correct?? Because in the end, like many of us, I use MAS, so even if I create the ISO with only Professional Edition, later I can change that to whatever Pro-compatible edition. The advantage is that I have a smaller ISO.
It can vary and depends on the selected SKUs. @abbodi1406 has more insight than me, could be that I ignored the compression. "The SKUs are almost equal, but some are more equal than others."

Both of you are the best!! Thanks a lot for everything So, I will make a new Win10 Custom ISO only with Pro Edition (without using "StartVirtual"), as it results in smaller size. Maybe in the "ReadMe" file inside "uup-converter-wimlib", in the section of "Virtual Editions" could have a little point that says something like: "Using this option increases the final ISO size a hundreds of Megabytes".
