How can I upgrade my 1809 version to 1903? Windows Update only offers 1909. The manual tool linked here(https://www.groovypost.com/howto/manually-install-windows-10-1903-may-2019-update-now/) has been changed to update to 1909 instead of 1903 so no luck there either.
Why not upgrade to 1909, because otherwise 1903 and 1909 are identical from 4. of October 2019, only some 1909 features are simply hidden for 1903, but they are there. But of course, if you want to see version as 1903, there is absolutely no limit to this, download 1903 .iso or .esd and upgrade to this version, but remember, if You haven't disabled major updates You'll get regurarely upgrade notifications. So, download 1903 and update.
Haven't actually tried one of these but all the recent Windows 10 builds are there, including two of 1903. This source was pulled off Microsoft's community forum and presented by one of their Directly people. https://tb.rg-adguard.net/public.php
Ah well I didn't know that. Usually a new version brings new bugs so now that 1903 had time to mature I was going to upgrade to that, and then later to 1909 when the next version is released. Thanks, nice source for Windows downloads.
