ISOs from UUPDump cannot be verified, as they come out a little different each time, even with the same parameters. That's the exact reason why they are not allowed to be shared here. To my knowledge, official 19041.1 ISOs were never released by MS.
Seems the same, not? You can't verify homemade/brew ISOs, as long as the conversion showed no errors all should be fine.
You said Code: Writing 899 files in 85 directories to 19041.1.191206-1406.VB_RELEASE_CLIENTPRO_OEMRET_X64FRE_EN-US.ISO Would you please kindly give me the link please?
