Use HeiDoc's Windows ISO Downloader to get an official, unmodified Windows 10 1909 ISO directly from Microsoft's servers. After download, verify the SHA-1 hash against Microsoft’s published values (searchable online) to ensure integrity.

Microsoft no longer prominently offers 1909 on its main download page, but the official Microsoft Software Download Dashboard (formerly the "Software Download" site) still provides access to older versions through a specific URL trick.
