While you should use Windows Update to install Windows 10 version 1903, May 2019 Update, Microsoft also supports several other upgrade methods using its Media Creation Tool.
You can download the Media Creation Tool from this Microsoft support website to download the May 2019 Update files to perform a clean installation, in-place upgrade, or to create an ISO file as soon as it becomes available shortly after the feature update launches.
Also, you can use the Media Creation Tool to create a USB bootable media, which you can use to boot your computer to upgrade to the latest version of Windows 10.
In the case that the tool doesn’t work, then you should try the Update Assistant, which is a tool similar to the Media Creation Tool. However, it’s been designed to perform an in-place upgrade only on devices where Windows Update isn’t working.
Microsoft is expected to begin the rollout of the refresh starting May 21, 2019, but it’ll be a gradual release, and it can take weeks until every device receives the update. Microsoft will start upgrading devices with newer hardware first, and then, when version 1903 has proven to be stable, the rollout will continue to other computers.
The Windows 10 May 2019 Update is just a relatively small and incremental update, but it’ll deviler a number of new improvements and several new features.
If you need to download the Windows 10 May 2019 Update ISO file directly, you can skip the Media Creation Tool using this workaround.
