https://forums.mydigitallife.net/th...view-build-16288-pc.75111/page-2#post-1370491 There are issues with WU.
The reports aren't about the ability to create editions, it's about the fact the UUP files are missing on MSFT servers.
Windows Professional Workstation is fairly easy. Download Windows Core Single Language and then follow this guide provided by @Enthousiast https://forums.mydigitallife.net/th...iew-build-16257-pc.74849/page-19#post-1364404 (ran everything in command prompt as admin) Worked like a charm for build 10.0.16288.1
i downloaded AIO turkish but missing files. İ try 4 times. ERROR: UUP Edition file is not found in specified directory Same error Enterprise edition
Annoyingly slowly x86 editions got released (ie parts of Polish, Portugese, Greek and even Core for Taiwan)
builds are arriving slowly, at least starting with x86 ones. Regarding your request, arm was removed by @mkuba50 so you'll need to ask him .
A fix can be download Pro en-us UUP files and use @abbodi1406 script for make a Spanish iso but the language pack aren't available in cab (yet)
