Have just had a download of Build 16296, and once again UUP to ISO worked perfectly.
Build 16296 has a watermark again, so not yet final build.

Hi folks, to any who still want to use System image from within windows 10.
the problem reported by me and many others, which started in build 16226,
has been solved in build 16288.
System image...

Once again a successful build 16288 and created ISO and burnt to disc.
Really happy with your work Kari and others

Hi yatznet

are you really after RedStone 4 preview already, as this build is part of the skip ahead releases UUP to ISO might not even work, but if you want to play with build 16353 you are alpha...

Thank you Kari and all the other helpful people.
I guess all the machines I have set up over the years have been MBR as this was my first failure (GPT system)
I will try both Acronis and Macrium...

Thanks for this tip I will try it next time I need to use the program.

Successfully made an ISO from 16215 using UUPtoISO.exe
did have to press control 1 before pressing 1 again and the program working as before.

once more successful with build 16179 this time, both before restart and after with windows.old

Created two separate ISO files.
one before the restart, and another after the new build was in, by using windows.old.
both were successful and identical in size.
burnt one to disc for security

Thank you Kari for your quick action on our behalf.

Sounds like a brilliant suggestion to me.
Have done that and will reinstall when I need it again.
Thank you
