With updates it installed fine too: https://forums.mydigitallife.net/th...005-pc-fast-rs_prerelease.81029/#post-1573426
In fact now I am installing from 19551.1005.200119-2343.RS_PRERELEASE_FLT_CLIENTPRO_OEMRET_X64FRE_EN-US.ISO but I have to chose not to allow setup to check for updates, drivers etc. Now I am at 30%
19551.1001.200118-2023.RS_PRERELEASE_CLIENTPRO_OEMRET_X86FRE_EN-US.ISO 19551.1001.200118-2023.RS_PRERELEASE_CLIENTPRO_OEMRET_X64FRE_EN-US.ISO
So, he didn't integrate updates, set uup convertconfig.ini to not integrate them and you will have 19551.1001 too, doesn't make it less homebrew.
We’re investigating reports that some Insiders are unable to update to newer builds with error 0x8007042b. We’re looking into reports that some Insiders are unable to update to newer builds with error 0xc1900101. finally!! 20H1 also wont install for many insiders as an upgrade.
That works to. When I said I deleted the KB's, what I meant was I moved them to there own Folder so I still have them just not in the UUP Folder.
I believe it will be GUI and the Core version as the new Server LTSC is due in 2021, which will be the 20H2 build. The Core non GUI version is better anyways.
