This build, 17129, is much time in its position. BTW, What the difference between making ISO with Standard install.wim and making ISO with compressed install.esd ? Am I loosing something with the option 2 ?
17115 x64 fits DVD5: 4.25 GB (4,572,461,056 bytes) and it even fits FAT32 max filesize <4GB for install.wim
If you check previous releases it's too early . It's not as if they compile and immediately release them, this involves some internal testing and evaluation first.
That would be against the rules, here you have a tutorial on how to do it yourself: https://forums.mydigitallife.net/threads/windows-10-esd-repository.59082/page-77#post-1380554
