You need missing files from x86 CoreConnectedN. If there's 8.1 Starter(N), you can have every edition. So if I were you, I find Starter(N). Or any editition that has Starter(N) files, alike Windows 7 Ultimate.
I will do that on Stater version (CoreConnected Single Language) But the CoreConnected N version currently no x86 files.
It seems that CoreConnected(N) is OEM. I had one Asus CoreConnected tablet installed 15063 PPIPro and ruined (EFI BIOS).
Q: What components are different between Oficial image and UUP package (esd files, not creaed ISO which uses the correct files in Core_xx-xx.esd and Professional_xx-xx.esd)? A: Three manifest files differ in SHA-256. UUP package Code: InputObject : "amd64_microsoft-windows-i..ymousauthentication_31bf3856ad364e35_10.0.17134.1_none_a89c519e7f93bc93.manifest" "5D5315EB4270DAA84DAD57E02BD2916B216B6D208E002EFCAB36A8BE53126CF9" InputObject : "wow64_microsoft-windows-i..compressionbinaries_31bf3856ad364e35_10.0.17134.1_none_99a7ae8b338cad12.manifest" "8714964C56CE6E56CE52BD0CEB84763BD2C37AB681FF8548B63D12936259E500" InputObject : "wow64_microsoft.web.confi..fileprovider-comreg_31bf3856ad364e35_10.0.17134.1_none_fc00a76c785fa88a.manifest" "D8B8567F7F72F4FB753D8B7C8B59E9DF6641F62CB2C91A53CA08A10B9394EF08" Official image Code: InputObject : "amd64_microsoft-windows-i..ymousauthentication_31bf3856ad364e35_10.0.17134.1_none_a89c519e7f93bc93.manifest" "CE0004F15ACC454951582C6C5377691408D493CD5E31D8E216AC1E21CDBBC20F" InputObject : "wow64_microsoft-windows-i..compressionbinaries_31bf3856ad364e35_10.0.17134.1_none_99a7ae8b338cad12.manifest" "8382E6F9184F8F9FB4AA7C363BEDC8B96C762CAD4D11312B12C7D9136AD3E99B" InputObject : "wow64_microsoft.web.confi..fileprovider-comreg_31bf3856ad364e35_10.0.17134.1_none_fc00a76c785fa88a.manifest" "41DC33D87CD9CAF78F64CEE5B7C56199B95F7A6FFBF4B0FFBB5FD3EF6A7E5622"
Yes. I've just found someone here made Win 7 (RTM) Stater to all version (incl. all N & E edtiions) tool. Although whatever127's Win 8.1 Script is Core N to CoreConnectedN, not from the Core edition. I will have a try on Win 8/8.1/RS1/21H2
