Cannot try this as no one has 16257.1 anywhere that I can find (all the mirrors report 404). Microsoft seems to have also removed it from their server as the UUP tool cannot find it either.
16251 is available at the techbench unlocked download options, i showed the old product,ini retail key worked on that edition too.
Alright, fair enough. I assume I am downloading the retail and not the VL ... Downloading now. Spoiler
16257.1 and 16257.1000 are real: https://forums.mydigitallife.net/threads/discussion-windows-10-insider-preview-build-16257-pc.74849/ But i am beginning to doubt the HWID activation story too, still testing. We have seen someone claiming a HWID activation before but that one was just doing what i found out first, and it wasn't HWID but by key from product.ini.
Yes, but it seems a bit convenient that an old preview is what she or he is claiming, which is no longer available, and she or he is not willing to share, while making that claim.
You can discredit me all you like.. Just search for yourself you will find themlf!! Adguard has them up as UUP'S cloudmail
All mirrors result in 404 errors as all sources have been pulled (which I stated before). Upload a source.
You obviously have not provided anything. I can sit here too and troll and tell you I have a copy Microsoft 10 Plus! and then I can tell you to search harder too. But unless I can back it up, it is all just talk.
