    Thanks for the update, good to know it works.

    Something important I want to say before any comments from those members of ours willing to split a hair whenever possible (yes, a global big forum like Ten Forums, we have members like that, too!):

    Thanks Kari for the reminder about secureboot, I tend to forget that. Probably because I have not used Hyper-V for a while. :-)
    Just a hunch on my part. MS ripped out a reasonably good chunk of telemetry code they no longer needed. Other code cleaning, too, I'm sure. Just a hunch......

    I have this same hunch! :-)

    ...speaking of ripping off components not needed anymore...do we have any good tutorial on this site for removing everything from a Windows installation that is not required. Similar to NTLite, but doing it all manually on an already running system?

    Another oddity, an interesting fact is that ISO created from UUP files is over 200 MB smaller than one created from ESD (comparing EN-GB 15014 PRO images).

    Both images work perfectly, installing Windows 10 without a tiniest difference.

    I wonder if this has to do with the UUP converter re-compressing a lot more files with better compression settings than the ESD counterpart?


    UUP converter, re-compress a lot of .cab files to .esd before moving on.

    Both same format? WIM or ESD?

    Both exactly the same WIM based ISO images.

    I think we should open up the two ISOs and do a file to file comparison to see what is different. Also taking a look inside the .wim could be a good idea. I bet some .cab files are smaller on the UUP version. Or maybe the .wim got better compression too?

    I would do that, but I don't have any copy of the latest ISO converted using .ESD download, I don't even have the .ESD file, only have the UUP version. :-)
