It’s always recommended to use Windows Update to install a new version of Windows 10 (such as the May 2020 Update), but 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 version 2004 files to perform a clean installation, in-place upgrade, or create an ISO file as soon as it becomes available.
In addition, you can use the Media Creation Tool to create a USB bootable media, which you can use to boot your device to upgrade to version 2004 of Windows 10.
If the tool doesn’t work, then you should try the Update Assistant, which is similar to the Media Creation Tool, but it’s a tool to perform an in-place upgrade only when Windows Update isn’t working.
Microsoft is gradually rolling out the new version starting May 27, 2020, but only for devices running version 1909 and 1903 will get it first, and then, when version May 2020 Update is more stable, the release will continue to other computers.
Windows 10 May 2020 Update is a relatively small and incremental update, but it’ll deviler a number of new improvements and several new features. (You can check the best features with this release in this guide.)
If you need to download the Windows 10 May 2020 Update ISO file directly, you can skip the Media Creation Tool using this workaround.
