You need to be a MSDN subcriber in order to download the latest Windows 1903 build from M$. Other methods is to search google for unofficial sources just make sure the checksum match the one on the MSDN site.
Win10_1903_English_xxx and all languages iso's in place but for now locked access (403 - Forbidden) is need date and time when up.
You did not understand well by what I said. I only said that the files are set but a decision is needed when they are online.
tb.rg-adguard.ne or Windows-ISO-Downloader.exe "all from here" is better to download windows version? I want only Windows 10 Pro x64 EN-US, so, where do you like to download iso's?
